Shadow problem

I did it a little bit differently, I created my basic level with the ball and the camera and then I created all the other levels that I stream as I went along. I put a static light in each level but I have exactly the same problem as at the beginning, always the same shadow problem. A new problem has been added: it looks like the lights are overlapping so the intensity of the light is increased in each level.

Here’s my persistent level with the 3 levels (i start with only the first one streamed)

](filedata/fetch?id=1788271&d=1594762862)
here’s the same level after build with only the first level visible
](filedata/fetch?id=1788272&d=1594763091)
If I go back and forth between 2 levels, I would still have a light problem on the right level I think because the problem already happen on the second level.

Maybe I didn’t configure the lights properly, is there an option to build the lights only by level?

EDIT : I managed to solve the problem of “overlaying” of lights thanks to the lighting scenarios but I still have this problem of shadows that appears at level 2
