The booster shows 2 but are grayed out so I got them spinning the wheel for free bonus. Please unlock them for me. It only does this when I win free pink circle wheels.

This normally only happens on levels which its not possible to lay boosters and special candies at the start due to the nature of the board. Which level is this happening to you on Cynthia?
