Sonarr, filebot, Plex (all pulling from tvdb), and the tvdb website itself, are all in agreement as to the episode number and title of some episodes in trying to add to my library. Jellyfin, also pulling from tvdb, insists on completely different information, in spite of the fact that it’s getting the series ID correct, so supposedly pulling from the same data as everyone else.

Any idea what gives? Can I fix this? I’m starting to vaguely remember that this might have been the singular issue that originally got me to abandon jellyfin and try Plex back when I was first testing out my options a few years ago.

edit for more information:

I was adding the recent 3-episode OVA of Reincarnated as a Slime. The TVDB page is https://thetvdb.com/series/that-time-i-got-reincarnated-as-a-slime/seasons/official/0

They are episodes S00E10, S00E11, and S00E12. You’ll need to be logged in and have your default language set to English, or it will default to showing the titles in Japanese.

My files are named using Filebot(using the same naming convention of the other several thousands of files in my library) as:

• That Time I Got Reincarnated as a Slime - S00E10 - Visions of Coleus To Coleus.mkv
• That Time I Got Reincarnated as a Slime - S00E11 - Visions of Coleus Great Phantom Thief Satoru.mkv
• That Time I Got Reincarnated as a Slime - S00E12 - Visions of Coleus Purple and Roses.mkv

The only change made from the information on TVDB, is removing a colon from the titles.

Jellfin decides that:

• the file for part one(E10) is actually titled as “Special - Coleus’ Dream, part 2”
• the file for part two(E11) is actually titled as “Special - Coleus’ Dream, part 3”
• and it decides that the file for part three(E12) actually does not exist on TVDB and has not match, and so uses the full file name as the title.

I have no idea where it’s pulling those titles from, or why it refuses to match them to the TVDB info. TVDB is the ONLY metadata provider I have set anywhere in Jellyfin, unless it’s not an option. And yeah, I have manually matched the show and selected the show ID linked above, even though it gets detected correctly automatically, regardless. I have also tried refreshing the metadata. Repeatedly. All of the other episodes, using the exact same filename convention, all match perfectly fine and get the correct titles, thumbnails, etc. Even so, I still moved the entire series out of my library and refreshed the library, doublechecked the filenames, and added the entire series back into my library. Changed nothing.

And yeah, I mean, I COULD manually edit the metadata on these three episodes. My concern is that I have many thousands of episodes in my library. Manually viewing, confirming, and editing each and every one is not an acceptable solution.
