the red badge is showing 2 emails when I only have one. When I open the email and then delete it, I go back to home screen and then it shows one. I have to go back in the email one more time to get it to go away. I do have ios9 beta installed so don't know if it's a bug but it only started doing it a couple of days ago. I've had ios9 installed since it became available. Can anyone help?
