HmIPW-WRC6 Lights not working

Configuration
1

Hello everyone,
today I tried to get the indicator LEDs on my HmIPW-WRC6 working. I can set color and brightness correctly through the “Light: Turn on” service, but it won’t change the mode of the individual channels to “always on” in the CCU. Furthermore it resets it to the off state when running my automation. Do I have to set this parameter manually by some means or is this a bug?

Here’s my automation code
