lightmap volumetric samples issue

Been stuck on a lightmap issue for days, one particular room, no matter where i change the lightmass volumes, no matter how many times i rebuild it does not place enough cells in that room, it acts like its an outdoor space with no static meshes near it yet the room it just a duplicate of others in my map which are fine… any help

This problem has been reported here also two years ago: Volumetric Lightmap sample and Indoor ArchViz Scene not working at all

It appears its been an issue for others but nothign back on the bug reporting : ?
