Booster not always visible in game

Squirrelwife

So, i am at level 6070. Decided to sacrifice one of my boosters (sprinkled chocolate ball) to help me with the game.

I couldn't do anything with it as it got immediately covered, and i could not use it at all when i finished the game, it stayed covered.

This is the 2nd time this happens, and i don't find it particularly fair not to be allowed to use a booster that i had earned previously....?

It just happened one more time. I figured i'd give it a chance, got another booster, that one disappeared under the covered square as well.

What's the use of getting boosters if you cannot use them.

This is the first time i am really annoyed at Candy Crush Saga.
