So I recently-ish upload ST: Deep Space 9 into my Jellyfin (kind of love falling asleep watching it) and some episodes are doubled.

For example in season 4 Jellyfin fetched the metadata for the episode 9 (our men Bashir) and put it on the episode 9 and 10. Now after 10 the episodes are sync on the one before them. It slightly annoying.

I checked the naming convention for the file, seems in order. Tried to refresh the metadata, to no avail. Reboot the server, didn’t work. Only permit Jellyfin to fetch metadata from IMDB, nope

I’m at lost, any idea ?

Edit : what worked was putting [imdbid-ttXXXXX] in the problematic files name and refreshing all the metadata for the folder, in my case all the series
