Grey ball affecting my material

Does anyone know what would cause my object to have a grey ball affecting the reflections after I export fbx? It was fine every time I exported before. Nice reflective matieral but it just started exporting with this grey or dark ball affecting it. I attached 3 photos of what it looks like now on 3 different areas of my object (building) I know I had to have done something but I can’t figure out what.

Yes this sounds weird… accidently copied some faces or extruded somethignin place ??? It clearly shows some smooth shading borders.

Maybe if you show the wireframe… ???
