Card Scramble Cooking the books hung the game

Playing Card Scramble Viola's Diner level 1-44, after using gems to purchase a couple of boosters, so that i had almost completed the round, I tried using Cooking the Books. It would not allow me to X out of using it, and would not allow me to bump the card either up or down. Essentially I was stuck. It would not let me use it, and it would not let me X-out. I had to abandon the round to clear the issue. As I said I had already spent gems trying to complete it, and had nearly accomplished it. This bug should be fixed, and my gems refunded.
