Light bleeding/tearing through walls when i move or am in a certain location!

I’ve just started working on unreal, I’ve been having this issue for sometime now. Whenever i move my camera (in-game or while making changes), the lighting just bleeds through different walls and glitches!
Also whenever i shoot the projectile by pressing, the wall for some reason glows and then goes back normal. Please help.
