Ok, if I could please have some help. Whenever I mask, I cannot move the masked clip over without having an outline of the edge. Let me show you.

So I open the crop window:

I Mask it:

Feather it:

But when I go to move it to the center:

How can I get rid of this? It would be much appreciated!

Thank you!!
