Missing metadata for new items until force refreshed - LeviSnoot - 2025-11-15

I'm having a bit of an odd issue which is difficult for me to troubleshoot as the logs don't seem helpful for it and I migrated to a mergefs volume around the time 10.11.0 came out, which incidentally seems to be around the time this issue started happening.

When a new item is added to my Jellyfin instance from a library scan, it seems that most of the time, the majority of its metadata does not populate for the item. Images work, but nothing else. I deliberately do not use Jellyfin's built in metadata grabbers, instead relying fully on TinyMediaManager to create NFO's and images. This workflow has worked fine until recently, where metadata such as titles, tvdb/tmdb ID's, year, plot/description etc. do not populate. I've found that if I force refresh the metadata for the item(s) in question, the metadata does populate. This is of course far from ideal, as it requires manual intervention from me in order to have a functional library. In the past, a regular library scan has been sufficient for the metadata to populate and update correctly.

If anyone has clues to help me I'd be very appreciative! To me it seems like a file permissions thing, but as you can see, my libraries have very open permissions. I'm not seeing anything in the logs that alludes to inaccessible files either.
