Lighting on objects coming from blender.

I am trying to learn how to build an environment in unreal, whenever I bake the lighting none of the shading of the modular pieces match. I have tried building my own lightmaps but that only seemed to make it worse. Does anyone know what I am doing wrong? I am using blender to model the objects. I also tried bringing in some basic modular pieces over from blender, but those didn’t match either. The mismatched lighting is even more apparent in the shadows and dark places.

I am also not sure what is happening in the corners. I have check my objects multiple times to verify there are no overlapping UVs.
