Content not showing in a new library

[IandJelly]

I've been using Jellyfin for a while now with two libraries, named Movies and Shows, without any major issues. I created a new library called Shorts (type Movies) and moved content from the Movies library to the Shorts library but no matter what I do I cannot manage to get Jellyfin to see it so no content is showing up in the Shorts library.

All permissions and groups are set the same between all libraries, 775 for directories, 664 for files and jellyfin group and user). I scanned for contents and the user I'm using has access to all libraries. Logs don't show any errors either. I tried searching for threads but I couldn't figure out what I am missing. Any help would be appreciated.

Is the new library located on an entirely different storage device? Or network share?

Is the new library located on an entirely different storage device?  Or network share?

The new library is on the same storage device as the two other libraries, like this:

/jellyfinmedia/tv
/jellyfinmedia/movies
/jellyfinmedia/shorts

I'm really stumped what it could be. I've been reading any post that resembles my issue, made sure there are no differences between the libraries that could cause this and checked all options but it didn't lead to any breakthroughs. I also turned on the debug log but didn't see anything out of the ordinary.
