i installed a new Leviton DW15S light switch.  the lights turn on, but they do not turn off at all. whether i push the switch button to On or Off, the lights stay ON.
i must have connected the wires wrongly.  i am including few pictures.  can someone please offer helpful advice? thanks [![enter image description here][1]][1]
