Greetings: going through the noise in layers tutorial video I reach the point where the morph brush is selected and in the video he paints out some of the noise. I have been through the video many times and the following happens each time when I reach that point. See image

I have tried turning off ZAdd / ZSub but that doesn’t work, I tried to work out if I am doing anything differently than the video and I don’t think I am. Help please.
