Cynosa Chroma flickering lights

In the last few days I have found that my Razer Cynosa Chroma keyboard has a problem with flickering lights. While the Chroma setting is active (+ Synapse is turned on) whenever the keyboard colour changes the lights at the bottom all flicker through several colours until settling. I also have a Deathadder Elite but that is working as expected. Does anyone know how to resolve the problem with flickering lights?
