I have this problem as well. I don't know what is going on, but Candy Crush Saga is very glitchy at the moment. I lost boosters, gold bars and lives a couple of times last two weeks and now I'm back to Level 1. It's getting so frustrating.
I had the same problem, haven't lost any boosters but really haven't been paying attention. Guess I better start doing so! I hope King fixes this problem soon, otherwise there is going to be some pretty cranky players!!!
