I would have to say that your frosting is to thick ...
Yes your frosting probably needs to be thinned out a little.
I have had the same exact problem with mine forever.....usually it's the consistancy. Try thinning just a little bit, and you can also use corn syrup to thin it, which will add a little elasticity to it. I also noticed that if my icing is super stiff, I can still make them, but make each pedal SLOWLY as moving too quickly causes it to crack and look rough on the edges.
