Style lost

I made changes in skin, everything was working fine and just working on admin panel “add to cart” button lost skin. All other is ok.

Cheking code I see that button has double suffix “action” - its “button-submit-action-action”. Where did I failed? Help.

Attaching the image.

Still can’t figure out about the suffix in style. Nobody has similar cases?
