Ladybug Radiation Analysis comes out weird - voids in its analysis?


I have formed a mesh using sweeps of a section that I converted from Brep to Mesh as my geometry. When I do radiation analysis of this mesh, some layers are blue and some are red in the same direction of the sun. This is very strange, I’ve looked at other answers about increasing the distance from the base, but I’ve increased it up to a factor of thousands and it still looks strange. Is it to do with my geometry? how do I get it to analyse my building uniformly? I’ve checked the mesh analysis and it looks correct.
