Complete my Album not showing some songs as purchased
I have a problem where not all the songs I've purchased are showing as purchased in the iTunes store. They are downloaded to my library and play fine but when I go to Complete my Album in the Store some songs aren't showing as purchased so if I complete my album I'll have to buy those again.
There's 1 album in particular where I own 2 songs from it but when I view it in iTunes store only 1 of them shows as purchased the other one doesn't even though both songs are in my library.
I've checked hidden purchases and it's not in there. Any ideas what going on?
Thanks
