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
