After update two transparent bars appeared on the edges

[Android Central Question]

On my Samsung Galaxy S8plus two kind of navigation bars appeared on the sides of the screen. They prevent me from using the digits and letters besides them when typing. And overall very annoying.

I have the exact same issue after the new UI update and it's annoying as hell. I've tried everything except for the factory reset. The bars actually function as a back navigation key when I slide my hand or finger across them, but I can't change their position or remove them no matter what I do.
Did you find the solution?
