Metadata issues and Tracks Missing from Music Library (Newly Added Files only)

Hi folks,

I’m running into a strange issue with my Emby music library that I haven’t seen before. Up until now, adding albums (FLAC format) has been completely straightforward. I just copy the files to my NAS, run a library rescan, and the albums appear in Emby without any problems.

Yesterday I added three new albums, but I noticed that some tracks are missing from all three albums inside Emby. In addition, the metadata appears to be incorrect or mixed up for some of the tracks.

Things I have tried

Removed the three albums from the NAS and ran a library rescan to clear them from Emby
Verified that all the FLAC files are intact and playable (they are fine)
Re-added the files individually to the NAS and rescanned the library (same issue)
Tried manually adding the MusicBrainz ID for each album (no change)

Has anyone encountered something similar or have any suggestions on what might be causing this? It's only happening with Music albums, everything else working as expected.

In case its relevant, I nest music as  FLAC > Artist > Album Name - Year > files

Thanks in advance for any help.
