2 albums I purchased on iTunes disappeared when I used iTunes Match. They are not listed as purchases but when I search on the albums, they are listed as purchased.

I have subscribed to iTunes Match so that I can access my music on all my devises. I had 2 Steve Hackett albums that I purchased from iTunes and downloaded to my iPad. After setting up match they have disappeared. When I go into the Apple iTunes Store and go into purchases, they are not there. When I search on the albums, they are marked as purchased, so I cannot redownload them.
