Hi! I believe the booster button is pulsing with a green color when a booster is activated. If you tap on it, non-active cards are on the right and the active card(s) on the left, within a green rectangle. However, if you have more boosters than you can store tapping on the booster button will trigger the dialog you mention. You will have to keep, swap or trash the extra boosters before you can do anything else. You should also have a little red number on the booster icon when you have too many boosters.
