Unread Email Count wrong for all eternity?

I've read a number of threads where people had the same problem but I've never seen a solution. My unread email count on my Yahoo mail is stuck at 5 (+ whatever unread emails I really have.)

I've:
--Double-checked all folders. There are no unread emails I'm missing
--Marked all emails as read in Yahoo just in case
--Deleted and re-added my Yahoo mail account on my phone
--Turned off and on, and done a hard reset on my phone
--Prayed, sang voodoo chants, and yelled at the thing

The false unread emails mock me. It's a minor annoyance but it bugs me because everything else just works so well that it sticks out.

Anyone have the same problem and solve it? Please?!

Thanks, Jeff
