UEFN Lighting issues underground/in tunnel

I have a tunnel going from aboveground to belowground and I am getting this weird lighting behavior. I’m not sure how to describe this properly nor what to do about it. These two pictures are of the same area, just at different angles. How do I fix this?

Just to add as well, I have the same/a very similar tunnel in two different locations without this light artifact. Not sure what to do here.

To add more. I’m not actually sure it’s due to the lighting from the tunnel from above to below. When I block off the tunnel entirely, this strange blue light still remains. There also appears to be a specific boundary for it as well.

This can be removed now, I found out for some reason a water body that was no where near this point was somehow producing this strange behavior. Still not sure how that’s possible, but it was the water body.
