Zbrush help - weird texture thing going on

Dayl

Hey guys, this weird thing happened, not sure how. It only shows when I turn on colorize under Polypaint. Did I bake polypaint by accident or something? Any idea what's going on and how to get rid of it?

If you want to clear polypaint data:
select a pure white color + flat color matcap, turn on MRGB, and go to Color: Fill Object

Awesome, thanks I had tried with RGB, but not MRGB
