purchases not showing

Last year I bought 2 tracks from the album I love Acoustic - Ministry Of Sound, today i bought another track from the same album, the only track that shows as purchased is the one bought today so if I wish to purchase the full album I will have to purchase the two tracks bought previously again. The two tracks previously purchased show in my purchases but when I click on the full album I am told the title is not available in the UK at this time, this is incorrect as I purchased an item today.
