K70 RGB Can't map an action to Return without disabling Return

Hey i just got the K70 RGB and i'm having trouble setting a KeyStroke Action that has a simple rainbow ripple to my Enter/Return key without disabling the actually return/enter functionality of the key,



Can anyone tell me how this works?



Also my backspace hold doesnt work, i need to tap backspace repeatedly to erase.. wtf??!!

For my backspace button i was able to assign a wave effect using a keystroke action... (Profiles->Assignments)
