Itunes has deleted my beyonce

okay so a couple of months back i purchased some songs off beyonces new album and about a month ago i noticed the songs were not in my library. I cannot find them anywhere - even on my purchases and downloads they don't come up, however when i go onto her album the songs i have bought simply say 'purchased' in the place of where the price would be. I can't seem to get hold of them and i'm super frustrated! i really hope someone is able to help! I've attached an image of what it looks like on itunes incase thats any help

thanks
