Skylights in streaming levels disabled in build?

I’m building an Unreal product configurator fow Windows over many product categories.
The persistent level includes only basic programming and I’m loading the product categories with streaming level, including own Syklights for every streaming level (I need to change the brightness of the Skylight and they are slightly different in every category so I need them locally inside the streaming levels). Only one streaming level is loaded at at time.
All Skylights are movable and the project is using Distance field Ambient Occlusion.

PROBLEM:
After deployment build the SkyLights in every streaming level does not work (lighten up the scene).

The problem persisted from 4.20 over to 4.21.

Is there any project settings causing this? Or possibly a bug? Or a thing that didn’t work on purpose?

Ok, I’ve found the solution in my case:
I had to disable the “Allow static Lightning” under Lighting in project settings.
Then the
Now let’s hope I never need static AND movable Skylights in my projects combined. (One level static and for instance another with movable).
I don’t think the checkbox should disable movable Skylights, it should disable / allow only static lighting.

Same issue here on our end.
This is not cool… What’s the reason for this to happen?

“Allow static lighting” did NOT work for us, but same setup.
