Minor Issues: Two shows sharing same TVDB ID.

[Smitty018210 184]

Just a weird/minor issue I ran into today and wanted to report. 
==================================================================================================================
One TV show missing from Shows but was still showing under Folders view.

I ran into a strange issue with Animaniacs (1993) and Animaniacs (2020).

Both are in separate folders and are supposed to be separate shows in my library.
C:\Tv Shows\720p\1\Animaniacs (1993) [imdbid=tt0105941]
C:\Tv Shows\1080p\A\Animaniacs (2020) [imdbid=tt6951546]

When I added Animaniacs (2020) to my library there was no issues. Both shows appeared in library. 
At some point (unknown time) it disappeared from TV show library.
I confirmed that the folder was still where it should have been and started to look for why it was not showing on main TV Show library list. 
I looked for it in folder view and there it was. Just where it should be.

==================================================================================================================
Knowing that other animated shows have weird metadata issues I thought that might be the issue so looked though the nfo for each show.
I noticed both shows had the same TVDB ID.

Animaniacs (1993)- TVDB: 72879
- TMDb: 82
- IMDb: tt0105941

Animaniacs (2020)- TVDB: 72879
- TMDb: 107124
- IMDb: tt6951546

==============================================================================================================================
It looks like this happens because TVDB considers the 2020 Animaniacs revival part of the original 1993 series, while TMDb and IMDb treat the 2020 version as a separate show.

There is already an older Emby thread about this Animaniacs metadata issue:

https://emby.media/community/topic/126569-probl%C3%A8me-de-d%C3%A9tection-dune-s%C3%A9rie/

There are also a couple of other reports where a show was available under Folders but was missing from the normal Shows view:

- https://emby.media/community/topic/133269-tv-show-doesnt-show-up/
- https://emby.media/community/topic/146230-tv-shows-are-only-showing-in-folders-tab/
======================================================================================================
Those had different causes, but the symptom was similar.

For my case, I removed the TVDB ID from the Animaniacs (2020) tvshow.nfo.

I left these IDs in place:

- TMDb: 107124
- IMDb: tt6951546

I didn't change anything on Animaniacs (1993).

Then I ran a normal library scan.

Animaniacs (2020) immediately showed back up in the main TV Shows list.

- No database rebuild
- No removing and recreating the TV library
- No moving folders around
- No changes to any of the other shows

Just removing the conflicting TVDB ID from the 2020 show and rescanning fixed it.

I understand why the metadata conflict exists since TVDB and TMDb handle Animaniacs differently.
======================================================================================================

Animated shows can get messy because TVDB, TMDb, and IMDb do not always group series the same way.

In this case, TVDB treats Animaniacs (2020) as part of the original series, while TMDb and IMDb treat it as a separate show.

======================================================================================================

The other strange part is that this setup had worked before. It only became a problem recently. (That I noticed)
I found a solution, but I feel that Emby should have still be able to see that they were different shows based on other IDs. 
So Bug? Database ID issue? Not really sure how to classify this.

That strictly depends on your primary library meta-provider (as that's the one used to identify an item): if you had TMDB as top-preferred one, you wouldn't encounter that occurrence (as those are two distinct entries with two separate IDs); if you have (and likely had) TVDB as the one, there's only a single ID and considered as same TV show.

I don't use emby at all for metadata. 
All providers are turned off.
I use TMM for all metadata.

[GrimReaper 5145]

And which scraper you use in TMM?

Universal TV show Scraper.
However I do have TVDB set for most, not all, scraper options for shows.

You should have main identifying scraper in Universal scraper settings, and that one will get "default" tag under <uniqueid> node in the NFO and is the one Emby will honor and behave accordingly.

OK, I will look into this, thanks.
I know this is small case sample/issue. I am sure not a lot of shows fall into this category. 
Any idea why it worked when I added the series to begin with? Then disappeared?

Do you have any internal meta-providers enabled in Emby? When you initially added those shows, was it with RTM only or full media library scan done?

None, disabled them years ago. 
After I add shows I always run full scan.

I can only assume full library scan was not yet completed at the time and you just haven't noticed the merging once it was through. But that's just an assumption.

ok, thanks. Like I said just a strange issue! 

[GrimReaper 5145]

Yeah, there'll always be some edge cases where different items share same external IDs (and not even from same provider or items of the same type) that will produce some unexpected results. But they can typically be resolved with a bit of manual intervention. Glad you figured it out in this case, though.
