I have no idea what CubeTheme is, but you'll need to make sure that the fold/call/bet buttons are a distinctly different color than the table background. Black buttons on black background won't work. Then remove and re-Include the site.
Also, you'll need to make sure that you're including the proper site within SaT. You would need to find out what built-in theme that CubeTheme is based off of, and then make sure that site is included.

I completely missed an easy possibility. Tables in the grid will only return to the stack when you click Fold with your mouse, or when you use a "Stack" hotkey. Maybe you are expecting them to return after your action is finished, which is incorrect.
