In the mask designer: select all masks (left top of the screen), and scroll to the top of the masks available. At the top left you will see a blue cross, which deletes the mask the has been selected in the screen right.
As you said it is simple, but whether it is intuitive?

Dont understand your second remark.

HAHA. Got it. So simple but I struggled and failed to figure it out. Thank you!

The second question: I have placed a mask (inverted) to hide a license plate. The fill is 100% opacity and black. How can I change the fill? Say to another color or even pixelated?

Thanks again!

A mask exists only to mark the area that is blocked or allowed to show through. It has no other properties.

In your case, you'd want to use an FX like Blur or one of the NewBlue Pixelators (if present) to place over the license plate. Each can be sized, placed and the strength of the effect tweaked as desired.

I tried it and it will work fine. The Blue Pixel apparently was a trial and expired but the blur works good. Thank you
