Lighting on Box FIght Map issue

In my Box PvP Map, when I first load it, the lighting seems normal, and the shadows aren’t as dark and normal. However, when I test the game and start it, the first round looks fine. However, when the second round starts, all the lighting in the match gets wonky, and everything is dark. I’m very confused about why this is happening, and I am wondering what I can do to fix this.

this is what it shows on uefn after the second round
