Items missing in library can be found with search, appear normally after playing

[zed423i]

Hello,

Only about half of the movies in a library folder are displayed in the Jellyfin library.

But missing movies can be found using the search function and can be played without problems.

After simply start and stop playing, the formerly missing movie appears correctly in the Jellyfin library.

I have not found any difference between displayed and non-displayed movies in the disk structure which could explain this, rescanning the library does not help, no errors in the log files mentioning the missing movies...

I'm running a fresh install of version 10.8.10 on Ubuntu Linux.

Thanks for any suggestion on how to diagnose / fix this.
