I'm in the process of setting up Jellyfin. The basic setup is easy enough (I'm using docker compose), but I can't make it recognize tv shows properly. The metadata lookup works for movies, though.
For tv shows, it returns a (seemingly) random tv show and assigns it to all tv shows in my library. So I end up with many instances of the same show in the UI. If I change the metadata source from TheMovieDB to TheTVDB I end up with a different show, but with the same result: Every show in my library is assigned to the same invalid metadata.
I can select shows and manually identify it, but that's really cumbersome for a big libary.
If also tried the same with Emby and I don't get the same error there.
I've also tried to but a tvshow.nfo file into folders to help the lookup, but it doesn't seem to be recognized at all.
I know I can put metadata on the folder name of a series (like the show id of themoviedb), but I really don't want to do this, as I have another mediaserver server (Kodi) the same library to my Smart-TV. It would mess up that libary - also: Emby seems to be able to do the lookup correctly, so why wouldn't Jellyfin?
Replace all metadata and check to replace existing images
Jellyfin main menu (where you see your shows thumbnail) > "three dots" > refresh metadata > replace all metadata > check replace existing images
If this works for the TV show you changed according to Jellyfin's recommendations, you can bulk edit your TV shows names and folders with Sonarr. You don't need to redownload them, just use your local files.
If this doesn't work check your Jellyfin's docker logs/configuration/metadata downloader
