Lightmaps are baking for each LOD when we do LOD's manually

Subj. When we doing LOD’s via Unreal AutoLod system everything works fine. But when we add LODs manually unreal begin to bake its own light map for each LOD. We exporting LODs from Maya using Maya’s LOD groups.

UE version is 4.27.2

Does anyone know how to solve this? We need all the LODs to use the same lightmap as LOD0.

I am also facing this problem, do you know how to solve it?
