Lighting scenarios, parameter collection, lightmass

I am trying to set up lighting scenarios sections, that are using parameter collection vector values as emissive. The problem I am running into is every thing works as aspect except when I change the parameter collection vector values. When I rerun lightmass, the new color value does not take into effect until I reopen the master material and move something and re-save. This can problematic since I have several materials. Anything you can suggest that would make this work more efficiently? Is there a way to force a material to save even if it doesn’t register a change?

Thank you in advance for your help.
