AT&T Galaxy S8 Changed icons keep reverting back to original

On my S8+, I've changed a few icons I don't like using Nova Launcher. The next morning, the icons have reverted back to their original look? What's going on?

That's strange. What icon pack are you using? I have not had that problem. I use Nova as well and was using a different icon pack for days. I got bored with them because I had been using them for a while on my V20 so for now I'm rocking stock icons but I was using the icon pack for a couple days with no issues. Maybe try a different icon pack to see if that one keeps switching back as well.
