Also this problem appears to be related to a problem I've been having:

Im just an iPhone user, and this bug has been driving me insane

I'm not a developer or anything (just a normal Apple user), and I have been experiencing this bug constantly (and I've factory reset my phone from scratch three times thinking maybe it was just a bad install or something). Especially with Apple's Mail app notificatons. I get a lot of Mail notifications every day, and when I swipe to clear one of them, the notification center dumps ALL of the rest of my mail notifications before I can act on them. It makes it extremely difficult to keep track of my emails. I get even more frustrated because it's difficult to find reports about this bug from other Apple users, and I really want them to fix this nonsense!
