I originally had my comcast email set up on my phone, but I didn't like the way it was handling it. So, I deleted those and loaded K9. But now, at the top on the notification bar, there is still an email notification with 25 unread that has (null) next to it when I pull it down. If I press on it, it doesn't do anything, just goes back to the home screen. How do I get this off of my notification bar??
