Issue with SMS/MMS notification bubble

[TotalLamer]

So... this happened a few weeks ago before I updated to the 6.5 VZW build, and now once more about a week after I did. There's the little green bubble above my SMS/MMS icon with a "1" trying to tell me I have a new message, but I have no new message. Both times this has happened I went so far as to delete the entire inbox, but the phone still insists I have a new message. Only reason this was cured the first time is because I flashed from 6.1 to 6.5... thoughts?
