S2U2 shows MMS message when there is no unread message

[themogul8]

I installed S2U2 a few days ago and absolutely love. Today on the screen it was showing 1 unread MMS message. Then a few hours later it changed to 2 unread MMS messages. I looked but there were no unread MMS messages. There was only 1 picture message from a few weeks ago. I soft reset the phone and it was still there.

I was finally able to get rid of it when I deleted the one month old message. Has anyone else had this problem? Any ideas on what might have caused it?
