I just changed the edge banding on all my doors and drawer fronts to 3mm pvc.  I just discovered that when doing that, the edge banding is changed for these parts in every spec group even if the spec group has a different material file.  I thought maybe it was just a glitch when I copied  and renamed a spec group it would hold onto the original setting, but that is not the case.  All material edge banding is changed within every spec group, not just the copied one.   I have several material files within all of my spec groups.  Edgebanding is the same on all of them, even if I didn't change it.  Anyone else notice this? 

Maybe this is a issue with other builds as well.  Just noticed it now.
