Selective exclusion of album tracks that are standard everywhere else?

Artist: Clannad, Album: Legend. If I buy this album on a disc in Australia, all tracks are available. If I listen to it on Spotify, all tracks are available. If I find it on Youtube, it’s all there and all tracks are linked to the artist. If I go to Apple Music, it’s all there. On Deezer though, tracks 3 (Herne) and 7 (Scarlet Inside) are “not available in your country”. I mean, obviously they *are* available because otherwise Spotify, Apple Music, Youtube and retail stores wouldn’t offer them either. Why is Deezer singled out for exclusion of arbitrary tracks on an album whose tracks are otherwise all available for listening? Whose interests are served by putting holes in an album’s track list on Deezer but nowhere else? … makes me question my decision to cancel Spotify to give Deezer a go instead.
