Momentary switches not working anymore, after setting parameter 20, it works again

this morning strange things are happening in my Fibaro network. Since this morning a lot of Dimmer 2 actors didn't respond anymore to the momentary switch action. Totally dead. I could switch the lights with the Fibaro App/Controller HomePage. I disconnected one module and reconnected but nothing happened when flipping the switch.

I don't know how I got to it, but I got into the actor settings and changed parameter 20 from momentary to toggle, saved. Switched it back to momentary and saved again and the physical switch is working again. 

 

The Dimmer 2 module just forgot that it can be switched? And is is faulty? And 6 dead at the same day? It looks like something is sending garbage on my z-wave network and the actors react on it changing random settings... 

 

Did anyone experience this behaviour? On the Internet forums I read a lot of z-wave problems, but almost all these problems are tracked back to coverage. And coverage is working exceptionally good, flipping a switch with my phone at the other side of the house is faster than light. Very strange.

 

I have two PhilioTech wall plugs, is it possible that these plugs make my  Fibaro Dimmer 2 modules go funky?
