Bug fix needed – Rune Gems - Block n Tile Crush Review

I love playing the game. I have played all 12 levels over and over and make sure I earn 3 stars for each puzzle. I'm on level 12 and on puzzle 5 will not give me any stars no matter what score I get. I want to move on to more levels but cannot. Please fix this.
