Parameter doesn't Fade if in a cue (Capture Ambient Light)

Need some advise on a Fixture for the Capture Vis Software. There is a Parameter in the Fixture for Capture, which is the Camera in the 3D view, called Ambiente Light.

In the Programmer it is listeted where intensity would be and I can Controll it correctly moving the Encoders, touch faders and so on. Can also slowly move the value up and down.

Once I however Record it to a cue it doesn’t Fade it rather snaps. Easy I thought I have to go to the cuelist and enable Fade All, but still it snaps.

I had a quick lock to the Fixture Profile and is that maybe wrong? It doesn’t have Fade Enabled for Ambient Light?
