template-light RGBW brightness does not work on scene call

[Volvox0815]

The problem

I use a template-light to control my own rgbw device.
I can control it via the UI perfectly, but when using it in the scenes module colors rgbw and on/off states are triggered, brightness is not reacting/being sent from the scene module it seems. Or better: it is sent (I got the state changed event in nodered and checked the msg.data), but containing the actual value and not the one that is stored in the scene.

Imagine I have just manually adjusted the brightness via UI to 81% (->207). Then trigger the Scene where It should dimm to 255, I got this data trigger in Nodered:

I can see also see no changes on the brightness field in the developer section (and of course also not in the linked input_number.daniel_kueche_rgbw_brightness):

Attached the yaml config of the light fixture and the scene fixture.

Anything I am missing here? If using the template-light for a normal dimmable light without rgbw it is working without any issues and updates the brightness as it should when calling the scene
