Capsule shadows render on backside of mesh

It seems as though when enabling bCapsuleIndirectShadow the cast shadows will project on the backside of a mesh. So if you have a character on a floor above you then you can see its capsule shadow on the ceiling directly above you. Its the same behavior as the old UE4 modulated shadows.

Is this intended? If so is there any way to get around it?

i have the same issue on 4.18.3, have you got any solution?
