Ive found a BUG!

Could you fix that when Im editing with Clarity on my photo is big square often darker than the rest of photo. Ive uninstalled it many many times but its still there.
I hope youll fix it because its my FAVOURITE editor and Im pretty sure that Ill never find great editor like this. Please do something with it because its driving me crazy!
