Why are Brush Masks disappearing?

Why are Brush Masks disappearing from latest image version but then reappear when using heal and clone tools?

I've attached a couple to images that show the problem or mistake on my part.

Previous brush masks of eyes only reappear when I use the clone or heal tools on the eyes. Then the bluer/brighter brush masks reappear as here:

But then go away when the clone or heal tool is completed. The eye masks do not show up in current version.
