Show Masking. HELP! LOL

When I click “show masking” on a layer the boxes which I have used to “mask” now are not visable.

What it does is show you the project how it looks when played. How do i turn it off? i want to see my boxes! lol. I tryed clicking the same button but bothing.

I got to it by right clicking on the layer then clicking show masking. This is the third forum ive asked and i hop you guys can help!:pleased:
