Galaxy S6 :: Text Message / Email Notification On Lock Screen

When I get a new text or email if I unlock my phone and touch the email or message app and read or delete it, it still shows the notification in the upper left. If I then lock my phone and unlock it again it still shows the notification on the lock screen. I have gone and cleared the cache and data from the message app and restarted. The only way it goes away is if I swipe it away on the lock screen or select it from the lock screen and view/delete after it opens.
