Collections deleted after update - frankmikalsen - 2025-10-08
Hi
Does anybody have a problem with the collections being deleted?
All the collections are found at Home/Collections, but they are all empty.
I think its a couple of weeks ago I had to put the movies into the collections again.
Had a look today, and all collections are empty again....
I use updated Unraid and jellyfin linuxserver that I updated today.
Thanks in advance

It could be one of two things, probably number 1.
1. There is a task that will remove items from a collection/playlist when the server starts if the item is no longer present. If your media is not detected when this runs, it will be removed.
Dashboard -> Scheduled Tasks - Clean up collections and playlists. The default trigger is "on application startup". Just delete that.
2. When you identify or scan with the replace metadata option, there was a bug that removed the item paths from the collections. That issue is solved in the upcoming 10.11 release.

Thanks.
Found it and deleted it.
Will put my collections together again and see what's happening.
This has never been a problem before. Never allowed this cleanup on startup.
Is there some updates that causes this?
Looking forward to 1.11 release.
Thanks in advance

So what's the solution to this problem? I had about 50 tv shows and now, none of them show up on Jellyfin. It happened with last update, so waited for the most recent one, thinking it might fix the problem, but still not fixed. All I get is a couple tv episode that show up and instead of the correct meta data, it just says "fun tv show".

I suspect your issue is different than the OP's, as his issue was with Collections, which are handled very differently than TV series.
From what you've said, my first guess would be that your file/folder naming structure is causing metadata mismatches, but it's very hard to diagnose problems without more information, what OS, docker/bare metal, jellyfin version, logfiles, etc.
