Tap on Notification and goes back to Clock

[Floridadomer]

Not all the time but lately more times than not, I get the notification that an email or text has come through. When I tap on it, it goes back to the clock.
I am tapping within a second or two of the notification so it shouldn't be timing out yet. The crazy thing is when I swipe to the Notifications screen, it shows none although it was never opened up. I can go to archive and find it so its not like its not there.
Has anyone else experienced this issue?
