Help! Facebook notifications won't disappear after I confirm game requests...?

[Lena R.]

Well, this morning when I checked my facebook, there was some friends request and also game requests (only cityville). Notifications for friend request went away after I confirmed, but notifications for game request stayed. I did all I needed to do, sent some presents and factory invites, it was 24 of them, and when I checked later, all the same game request were there again, it looked like I didn't accept any of them... So I have 24 old and every minute more and more new requests, and any of them won't go away. It's not up there in the blue area with red notifications (sorry not so great with english), but on the left, on the home page, under the picture and groups... It never happened before. IS THERE ANYTHING I can do to make them disappear. I'm confused now, don't know which of them I answered and which ones I didn't... and my friends are sending new ones to help them out with their cities...
