If you will provide upscaled LocalSpace instance as Spatial parameter for object scattering - it will drop modified settings to default 8km X 8km size and you node will have such view:
- full world is LocalSpace with 50km x 50km size - and little buggy square that is drop own 50km x 50km settings to 8k x 8km
without bug the object localspace should be same as generallocalspace of node
