Everytime I download a movie. I keep getting reloads on several t.v. shows i have already loaded

It's really hard to explain...but I'll try my best to explain. Everytime I get a digitial copy for a movie or t.v. Once I have it redeem and downloading. My Itunes shows that I have Game of Thrones season 1 and 2 downloading too. But I have it already downloaded. I've tried deleting and also I let it reload too. But it keeps coming back everytime load a new movie. It's very annoying!! Please help!!
