Lighting autobuilding?

Is there an option to auto rebuild lighting when I start my game?
Because everytime I start it using my MainMenu widget the enviroment looks like I have 2 spot lights in one room.
I don’t use the Default DirectionalLight in my game because I want it to be darker.
I use some SpotLights for lighting some parts of the floor.
But when I start the game it looks like I have the DirectionalLight on use.
Even if I use Set Actor Hidden in game when I start it.
It looks like this:

When it should look like this:

I can’t even see my decals!

I have the same problems. I even deleted the directional light, and the scene still is illuminating like if it was there. Even after rebuilding the lights. I think unreal engine still have so many ligthning problems all around…
