2nd switch cannot change power state with Samsung Smart Button

[swindiff 0]

Hi There

New to this forum and Z Wave - Fibaro equipment, hope you can help with a simple question.

Got a Samsung Smartthings 3 hub, Fibaro double switch 2 and a Samsung Smart Button.

 

Fibaro switch is working great, got it controlling an external reactive switch and a normal light-switch (will probably change this to reactive too).  These switches will be located outside on my shed.  One will be the shed internal lighting and the other for some outdoor string lights going round the outside of the shed and along some fence panels.  I want to be able to control both switches with the smart button just inside the back door.  Smart button works with single click, double click and hold and these actions can either power on,  power off, or change power state on/off.

 

So the first channel of the Fibaro switch works fine, can get it to action power on, power off and change power state.  However with the 2nd channel power on works, power off works, but change power state does not work.

 

What I wanted was single click to switch on and off light 1 and double click to switch on and off light 2, but I cannot get this to work. 

 

As a workaround I have it set up like this.

 

Single click - Change power state of switch 1 (on/off)

Double click - Turn on switch 2

Hold button - Turn off switch 2

 

Does anyone know why change power state on the 2nd switch channel does not work?

 

Thanks
