Multiple level build data being created on Building Lights

Just upgraded to 4.24 and I am experiencing mulitple built data files being created when I build lighting. Only one is necessary and that is my light level. When i close and open the unreal file, the scene prompts me that those built data files are missing. When I go to look for them they are missing. I have Force No Precomputed Lighting unchecked. Does anyone have any suggestions?
