BB Bold 9700 :: Email Indicator Pops Back Up After Reading Msgs

The problem I am having is that when I receive an email, I will open it, read it if need be and either leave it as is or go back to the home screen. A few seconds later the email indicator shows back up as a new message, like if I havent read the message. If I retort back to opening it again, a few secs later, the indicator pops back up. So in order to get rid of the problem all together, I have to simply delete the message which takes care of the problem.

Is there a way I can get rid of this problem without always having to delete my messages? I have tried deleting my email account and adding it back, but the problem in fact remains. I have gone thru the options menu to email setting and changed some things in there just to see if that would fix it. But nope, the problem still remains. Can someone please tell me what the problem could be and how this can finally go away? thanks in advance.
