Problem with physical switch S2 on Fibaro Dimmer 2

[codowd 7]

Hoping someone can give me a steer here.

 

I have a light on a Fibaro Dimmer (S1) and I have associated S2 on this dimmer to a Fibaro RGBW module.  S1 and S2 on the Dimmer 2 are physically wired to a wall plate.

 

Switch S1 works just as expected.  Also on the Web UI switch S2 works as expected.  However Physical switch S2 does not work - no action whatever.  Nothing recorded in the Fibaro event log.

 

Now I know the physical wiring is OK - when I turn on Parameter 29 on the Dimmer 2 to switch S1 and S2 then the behaviour is replicated on the opposite switch. 

 

What am I missing?

Possibly the option 20,23,26 and 28 on the device?

Look at the bottom of the support site
