I've come across a weird artifact/bug concerning albums where different tracks on the album are performed by different artists and the Album Artist is a different name, say "Various Artists".
If I access the album through the Album Artist category and then "Various Artists", all tracks (and the album itself, obviously) are displayed with their artist as "Various Artists", whereas if I access the same album through the Album category, the tracks now have the correct associated Artist against them; however, the Album Artist is not "Various Artists" but the Artist that happens to be assocaited with the first track (e.g. "The Definitive Burt Bacharach Songbook" is shown as being by Dusty Springfield because she performs "The Look Of Love" on track 1 - all tracks have the Album Artist tag set to "Various Artists").
My current version info is the following but the bug may have been present in previous versions without me noticing:
