unexpected shadows after baking lights on static objects

I have this room that I have checked as static. I also have two directional lights in slightly different angles. After baking the lights, there are unexpected shadows on my walls and they are just not as bright as they should be. I have tried to read more about unity lighting but I'm not sure what's going on here.
Pretty much all objects are set not to cast or receive shadow either.


The skulls (on the right side of the room) are not receiving any of the light it seems and they are always dark even though my directional light modes are mixed. The shader on them is Mobile/Bumped diffused because i'm developing for VR headsets. Is that not an appropriate shader?
Thanks.
