Problem with lighting

I have a problem with lighting, the thing is that when I put a light in front of the door, it shines behind it.
I don’t know if someone knows why it happens and how to fix it, but that would help me a lot.

I’m starting at ue4 and I don’t know much about this and I’m sorry for my bad English, I’m from Spain.

I attached some photos so you can see the problem.

I’ve seen this before and can’t remember the answer, so I’m grabbing at straws, but I think it’s something to do with the door material. You have to make it two sided, or not two sided, I can’t recall which…
