Linear WS-15s-1 Switching twice

After the last couple updates I've noticed my one Linear WS-15s-1 double tapping (on off on) when turning on through z-wave commands, but not directly at the paddle.

Hitting poll and refresh when the light is on also causes a double on/off flash.

Anyone have thoughts as to why? I'm using the genetic z-wave switch driver.

Failing switch, replaced and all is good.
