SOLVED: Non-english metadata

[Venson]

Unfortunately, that's not working either. Here are the steps I've taken: 

1. Deleted the audio files from the library
2. Re-scanned the library (no longer in Jellyfin)
3. Deleted the metadata files from var/lib/jellyfin/metadata
4. Un-checked/disabled all metadata providers from my music library (see screenshots)
5. Copied files back into library
6. Re-scan
7. Metadata is still not from the filenames

Oh no, metadata is not pulled from the filename but from the embedded fields of the media file.
