This is my second set of switches as I returned the first set by suggestion of Customer Service Rep on KASA. My problem is. 

I can turn the light on with switch A and turn it of with switch A. When I turn it off with switch A, I can not turn it on with switch B.If I turn it on with switch A and turn it off with switch B then I can turn it on with switch B. But when I turn it on off with switch B, I can not turn it on with switch A. The switch that turns it off is the only one that will turn it on. I have it correctly wired with the black wires as the travelers, the red connected to the side , white connected to white and ground connected.
