Found out how to correct the problem.  For Will and Penny, enter the Apply Rules for their VSS, and disconnect the eyeball node from the Template Eyewhite  rule.  Reload your original characters, and then reapply VSS.  In this particular instance, Will and Penny's material zone textures do not match those of the Kids 4.  VSSProp would need to be reworked to accommodate the different material zone arrangements.  This is a quick fix and it should correct your problem.
