Z-Wave parameter not saved (Fibaro Roller Shutter 2)

I have several “Fibaro Roller Shutter 2” and I want to disable all my roller shutter wall switches when alarm is triggered (so the thieves cannot open or close them). This device has a special parameter to do it, but when I set it (I tried it using HA frontend Z-Wave Node Management) it returns to its original value after a few seconds.

The device is working perfectly, so the z-wave communication is fine. Any idea about how to achieve it?
