My messages screen (text log) has inverted the colors but no where else on my phone has! s7edge

[AC Question]

Today walking home from work I was talking on the phone with my Mom and when I arrived home my messages screen inverted its colors. The actual conversations are normal colors and every where else on my phone has normal colors. Just the screen that has the list of all my conversations has inverted the colors. I almost thought maybe it was the theme but the theme is completely different colors then the colors being displayed and the rest of the phone is fine. After trying to find something on the internet as to give me an idea it just gives me the directions to uninvert the entire phone. I've gone through my settings and clicked and unclocked everything I can think of. But nothing seems to work. I went on Facebook and no one has the answer. So I'm taking to this forum. Does anyone have an idea as to what is going on with my Samsung galaxy s7 edge messenging log/screen?
