Liquify Screen does not show brush only the Hand icon
I am trying to liquify a layer and when I go into the Liquify screen, the brush icon changes to the hand and I cannot change it back. When I click on the mouse, you can see the hand "grab" to move the image, but nothing else. The Brush tool options are available and changeable; the Face Aware liquify works properly, but the Forward Warp and all of the tools are selectable, but you cannot use them. Only the hand icon shows. Any help is appreciated!
