How do i get ride of a notification that keeps poping up on my screen

[SaucyKay]

I have a Galaxy s6 edge
When i get a snap notification it pops up on my screen but its in the uper center of my screen in a box not just in my notifications drop screen, it only happens when i get a snap chat notification. Iv tryed deleting an re downloading the app but it is still happening.

I have a pic to show but idk how to post it atm
