I'm seeing this issue all too frequently with some albums on my Apple TV. When I try to search for an album, the tracks are not grouped within one album. Instead, the Apple TV creates duplicate list items (different tracks though) resulting in not being able to play the album all at once.
The weird thing is that they group fine into one album within iTunes itself. One of the albums displayed in my screenshots below was even bought on iTunes.
Any help on how to get it neatly grouped into one album?
P.S.: Already restarted the Apple TV and logged in and out. Using iTunes Match
