Hi,
First of all, sorry for the delayed answer, life got in the way. Fortunately @yindesu already provided some logs (thanks!).
I’m using two different Picard versions on different machines and I just checked with both of them.
The old version 1.4.2 is not able to match the recording by AcoustIDs at all:

The new version 2.7.3 is recognizing the recordings, but it displays them as non-album recordings. This is incorrect, because they are assigned to an album. I guess that’s the same problem @ulugabi has seen:

The logs above are for the first track only, I removed the rest for brevity. Logs about other tracks are similar.
The acoustic fingerprints calculated by both versions are similar, but not exactly the same (I guess this is expected, there are different ffmpeg versions on the two machines I tested on). However, after scanning both Picard version show the same AcoustID e7f91c79-36d2-4407-b3c1-626647795925
in the “New Value” column in the GUI.
For the record, most of my music files are recognized correctly in either version of Picard. It’s just the AcoustIDs that I submitted recently that have this problem.
