An app I don't own in updates list

So I'm updating the software on my new iMac and I see that for some reason, "Angry Birds" is in my list of updates. I've never purchased this before. When I click "update," it comes up with this weird Russian generic sounding email address that I have no idea where it came from.

I'd like advice on how to get this removed from the list. A search of "angry birds" in Finder reveals only the .ipa file for my iPad version in my iTunes folder.

Screenshots attached.

Thanks! I really have no idea what's going on here.

 

I ended up buying it, but at one point, yes. Thanks for the solution!
