Layer mask moves all layers in group
Hey guys, I'm trying to create a texture with photoshop and now I'm having trouble using a layer mask.
I need to create a layer mask ontop of a group containing two layers.
Before I create the mask i make a selection of the group so only a part of the group will be masked.
Now I need to move the selection to another place but when I move it, all the layers move, too.
As you can see in the picture below i moved the selection (it's the white space on the mask) from the left of the viewport to the right edge. But the other two layers also moved to the right and that shouldn't be. I know that you can remove the link on the mask but that's not how it's supposed to be since in the tutorial i've watched he has the link still on, too and it works. I tried it on my friends computer and it works there, too.
Does anyone of you guys know if I maybe have some weird settings which are causing this problem?
Thanks a lot!
