Dark Shadow and Lightning problem when simulating

Hi, I am currently developing a VR game with VR template. But, I have problems with lightnig. I only have spysphere, skylight and directional light as in the template, however shadows are too dark as in the picture.

Then, when I simulate the game, the shadows disapper and everything gets shiny. Any idea what can cause that problem.

I solved the problem by changing the lights to movable
