Cubemap and shadow problem

Hello, i have some trouble with cubemaps and shadows in my map. I hope you can help me.

I did everything as it should, placed env_cubemaps, buildcubemaps in console and restart Counter-Strike but paintings still give wrong reflections and some props are lit up in the dark.

All prop_physics seems to be giving off shadows only in the direction of the light_environment and not to the surrounding lights. Creating very weird unrealistic shadows.

Put a cubemap next to the picture.

For the shadows, you are stuck with those.
