Anyone know what would cause this issue in game (screenshot added)

BUMP because …come on kids lets get to the bottom of this.

so I noticed that the DISTANCE FIELD SHADOW DISTANCE on Directional Light was at 8600. I lowered it to 7200 and the shadow SEEMS to have gone. I need to test it on another PC to make sure.

but now its like…REALLY bright in my level, even the caves…if you see the cave area in the distance, it looks like its daylight until you get closer. Obviously I can’t have this.

I really would love to talk to someone who has experience with the lighting for Day / Night cycles.
