Always says 1 new text message

[devicemanager]

Has anyone ever encountered the 1 new text message indicator never clearing? I have cleared all texts that were in bold and even deleted all recent messages - still can't get it to clear. Have done a soft reset, yanked the battery, turned off the touch flo and turned it back on. Anyone know what do do next. This is the 2nd time this happened - 1st time did a hard reset but that cant be the only answer.

Only apps installed are the registry editor, siriuswm6, inbox extender and s2u2...
