Rainbow streaks!

Hey guys... I seem to be having issue with my rainbow streaks, so when I’ve passed to rainbow streak no3 I get my cookie, bomb and double fish. Which would be brilliant except I am not getting the double fish, when the level that I’m on opens up and  the fish swim across the screen before I make my first move but yet when I’m actually playing the level I only get one fish at a time not double....?? Anyone else having this issue??
