OK, so I figured it out.
So, I figured out it was the cylinder shapes from the starter content that were the problem. In the pic below (which is how I wanted the scene to look), the cylinders are placed in the map, but I haven’t built the lighting with them in the scene yet.
This picture shows the cylinders in the map with the lighting built.
I’m not sure why that happened. If anyone knows, please do tell.
