Find Hidden / Deleted Music?

iTunes was showing me the same album that I purchased from iTunes Music Store twice. So I selected one of the two albums, selected all the songs, pressed CMND DELETE and hid it too and both disappeared.

I go to the iTunes Store, to that album, and it says I can buy it. It doesn't say I can download. Does anyone know how to get this to work correctly? Thank you

Seriously, why can't Apple get their own apps to work with their own OS on their own hardware using their own music store???

Thanks
