Need help with Surface Lights randomly breaking

I was looking around a map I made after updating to the future lighting category, when I noticed than in a single area of my airport terminal, the surface light, which works in the rest of the terminal to adequately light up the area via a part above my ceiling texture, randomly stopped working in that area.

Does anyone know why this is/how I can fix it?
It works perfectly fine on Voxel and Shadow Map

Edit: I’ve fixed it by using multiple different light models instead of one surface light part.

I dont work with GFX, Lighting etc, but it may be an overload or some stuff.
I doubt its the case.
