Reminders App: badge icon wrong count.

The badge icon that displays the number of reminder alerts is a welcome addition for me in iOS 6. However, I'm somewhat annoyed that it always seems to be incorrect. After a new reminder alert takes place in notification centre, you would expect the badge icon to update, but it doesn't. Opening the App and closing it does nothing either. The only way to update the count, is to re-boot the iPhone. Can anyone tell me how I can submit a bug report for this? Many thanks!
