Fondant deco on top of cream cheese frosting

Hi! lately i have a problem with my fondant deco. I made 2 dozen of red velvet with cream cheese frosting and using fondant decoration on top of cream cheese frosting. The fondant deco is brightly colored few hours later the fondant deco starts to become very sticky and melts size way, the color running into the frosting as well. I was very frustrated when i looked at it its was very awful and i can’t deliver to my customer. My question is should i not use any fondant deco on top of cream cheese frosting ?

Thanks for reading i hope to have a solution on this.
