Any file with this filename will not be added to the library

[gu5gus 0]

I just discovered that any file with a particular filename will not be added to the library (of a movie type library). The filename originally was "Ex Machina (2015) 1080p x265", and after experiments I found that "Ex Machina" and even "Ex" were not being added. Perhaps there is some string sanitation in the code that rejects "Ex"?

After scans, the file is also not present in the Metadata Manager. I have around 5000 movies in this library and this is the only file that has this problem. This file used to be in the library, but I'm not sure how long ago the problem started. I can say with certainty that 4.9.3.0 and 4.9.1.90 are affected. I think I was last aware of the file being present in the library around 2 years ago, unfortunately between then and now I don't have any further data. 

I'm happy to supply logs of a library scan or anything else if someone can please let me know how to get such a log.

Hi, what makes you think it’s not added to the library?

[gu5gus 0]

1. It's not showing as a top entry in the library when sorted by Date Added

2. It does not turn up in search results

3. It is not listed in the Metadata Manager

4. It is not alphabetically where it should be in the library when sorted by Title

It was likely merged/multi-versioned with some other item in your library. What are your library enabled meta-downloaders and in what order? If you don't have many multi-version movies, you can filter for duplicates and find the one that doesn't belong/should not have multiple versions.

1. TheTVDB
2. TheMovieDb
(these were the default settings at the time of creating of this Movie-type library)

I discovered the area where I can filter for duplicates. About half of the duplicates are correctly grouped, the other half having grouped two or more unrelated movies together. How do I ungroup them? Regarding the movie in question (Ex Machina), it is not in any of the duplicates.

Move TMDb on top (or disable TVDB altogether), rename your movie folder to "Ex Machina (2015) [tmdbid=264660]", run Scan media library task.

In each item details there's a "Split Versions Apart" button lower down, split items, re-Identify incorrectly identified ones.

There's actually not the usual Split Versions Apart option for any of the duplicates in this library. Instead I have these options (not showing is Add To Collection because I scrolled down)

Edit: Add a second screenshot with a clearer view
