wiz lights with scenes and effects?

[x130844]

Hi,
I can't get the scenes to work with effects. It works with my other lights, like HUE for example.
For Wiz, if I save an effect for a bulb inside a scene, i reopen the scene in edit mode, the effect is gone.
If I activate the scene, it only reads the color wheel. What's weird is that the scene yaml file shows the effect, just not read in the scene editor, nor used when I activate a scene.
I tried with device and entities. same result.

What am I missing?
