Fibaro FGWP102 plug LED light when on

I am using a Fibaro Plug FGWP102. And the basics is working fine.
But I have seen this plug showing a white LED on the LED ring when the plug is turned on.
But after I have included the plug on my HASS with Z-wave JS it will only show a short flash of white LED when it is being turned on and off.

In the Configuration V1 tab in the settings I can see the paramter (41) for LED color when On, but changing it doesn’t change anything on the Plug!

FW on the plug is 3.2.

I have even tried setting the parameter manually in the bottom of the Configuration tab.
Refering to the manual from Fibaro the parameter is correct.

Any ideas?
