Sometimes when I use Scan button on some local files, if the AcoustID is missing from the database it is not getting written into the file's tags. If I then match the file manually to one of the recordings and press Submit AcoustIDs, nothing actually gets submitted.

I only work with FLAC files and this problem is somehow random. At the moment I have found a file where it doesn't work. If I select a single file, right-click and select Generate AcoustID Fingerprints, nothing happens. The expected result, is that an AcoustID is written into file's tags, and the file is marked as 'dirty', so it can be saved.

There's no errors in the Help->View Error/Debug Log.

If I manually generate the fingerprint, it gets generated properly, for example using this command:

> "C:\Program Files\MusicBrainz Picard>fpcalc.exe" "C:\Users\{username}\Downloads\Pascal Schumacher, Maxime Delpierre - Drops & Points Reworks [2018]\01. Gogopoints.flac"

I don't really understand where else to look for errors and what to do next. I will appreciate any guidance.
