Perhaps you renamed the files to a conforming name schema only after they were already (incorrectly) matched.

[optional: disable the SubZero plugin if installed]
[only when “treating” music, step 4 can be omitted]

- do a
Scan Library Files
in the web app (not ‘Refresh all’) Empty Trash
- “Clean Bundles”
- double check naming schema and move files back
-
Scan Library Files
again
[optional: re-enable the SubZero plugin if installed]
