Programme data is different on the search sites (tvdb etc) how do I fix it in emby?

[Cluttered 15]

The channel 4 program "GBBO Extra Slice" is at https://www.channel4.com/programmes/the-great-british-bake-off-an-extra-slice they have the series listed as 8-15 (it is numbered after the main show and a couple of earlier series are unavailable). 

Unfortunately all the other sites tvdb for instance https://thetvdb.com/series/the-great-british-bake-off-an-extra-slice  number the series differently they start at 1 and run to 11. That is numerically correct as the follow up show didn't start until the main show had been running a while. Channel 4 in their infinite wisdom have decided to number it in line with the main show rather than starting at 1.

So TVDB/IMDB series 11 is actually Channel 4's series 15. Tvdb's series 4 is Channel 4's series 8.

This means that I have files in seasons 8-15 but they match incorrectly or not at all because they don't match up to tvdb's 4-11.

I'd rather keep the channel 4 series number's, they produce the programme and it matches with the main programme (GBBO), Is there any way to correct it?

HI, if you want internet metadata from tvdb then you will just have to bite the bullet and follow their numbering. The same goes for Tmdb.

Alternatively you can lock the series and handle everything manually, although that will be quite laborious.
