Email Notificaion Tflo red "bubble"

[Sponge14]

I have an alert of 1 email on my touch flo ribbon, the one on the bottom of the screen. I tried sending an email and reading it to clear the, "1" new email alert. When I got the test email, it made the alert to, "2". When I delete the test email, it brings the new messages back to, "1". How can I clear the counter back to Zero?
