All your layers aren't shown because you have a small scroll bar you have to move to see them... but you will only see 2 when the flip is active, you'll see three when the Kerry pic is active, but only after you drag the flip onto it...

and only your text drags because you don't have it linked to the flip. Click beside the eye icon on the flip layer in the blank gray square, and you'll see a link icon appear... whatever is linked to the selected layer (the one with the paintbrush icon), that's what will stay together when you drag it.

When one image disappears, drag the one that stays shown out of the way and see if the one that disappeared is behind it. If it is (which should be the case), position the one that's disappearing differently so that enough of it shows after it goes behind the other one, to drag something onto it.

Also, you missed two white background spots, click once on each spot with the Magic Eraser Tool.
