Lighting director problem turning on 2 lights same time

I have set up to run 2 identical dimmer switches (schlage) , time based (to go on and off at a given window of time) , set days of the week and all is well with one of the two lights I checked off. I can turn the device on and off by phone but nothing doing on the smartapp. If it works by phone I would imagine it is not a distance issue. The list shows which devices I want to use -checked the two lamps and this seemed pretty straight forward. Any ideas? I am learning as I read more community support.
