LightMix is not updating material of the scene (DB 1.5)

Hi all

The ball on the scene is a xref file, when I change anything on the material of xref file the base file not updating the light mix on the scene.

I am not sure if I understand this correctly. Can you explain how this scene is made? What is xref’ed, what is “base file”, and what settings are you changing?
