I made a number of changes to one of my models which included a couple of small components adds, around 20 decals, and color changes which were done using display states. 

Since the file monitor feature is known not to work correctly I have been creating a new project file each time and importing manually. None of my changes are visible in Visualize. No new components, no decals, no color changes. 

I double checked the file names and locations. It is pulling it from my know location. I've double checked the active display states. That's ok. 

I can pull in the individual sub-assemblies and can see the display states, components and decals. But not when I pull in the full assembly, even when the correct states and configurations are active..

Thanks in advance!
