[quote="Lowlander"]Probably because Album Artist is missing.[/quote]
You're right, thanks. I tried checking both Artist performing tracks and artist who created the album and updated the file, and then the album showed correctly. But still, it worked fine in previous version and should do so in the new. it should be fixed in next update.

Probably because Album Artist is missing.

After updating to v. 4.0.2.1462 some albums are missing when you open artist node but you can see the missing albums when you click artist node. Fx. you have an artist with 5 albums but only 3 is shown when you open artist node. When clicking artist node you can see all 5 albums in the list.
