A purchased movie is not displaying under "purchased" on apple TV, I already owned a digital copy from a DVD combo pack and repurchased it on the apple TV and it doesn't show under "purchased".

I purchased the Despicable Me movie on the apple TV and it doesn't show up under purchased on there. When I try to purchase it again, it states that I have already bought it and asks if I want to watch it now, when I accept it takes me to the iTunes extras preview and I am unable to watch movie. It still displays the price on the store instead of "play" like my other purchased movies do. Any help would be appreciated
