My Gems disappeared! – Crazy Cooking Star Chef Review

I was playing my game, I leveled up and watch the video for double gems and coins. I went up to 10 gems. Then I watched three more videos and got three more gems. I just sat back down, thought I’ll play my game, and my Gems are not there anymore! What the hell is going on???? Please answer me!
