Lighting completely broken

I am posting because this happens in many areas, not just this door.

I have a simple door mesh with a light on the other side. I am completely surrounded by 5ft thick cubes, top and bottom too. The door is 2ft thick. There is also a cube inside the door that is 6in thick. I have a rect light on the other side of the door, brightness at 10 lumens…

Light still manages to get through the door

This happens everywhere, light leaks in walls and all. Tried with 3 different door meshes. Mesh has two sided shadows and lighting enabled.
