Okay,  to rule out installation problems I installed  "Hungyus School Girl Uniform' in the P7 Pro runtime directly. Which Also Contains the V4's geometries and morphes and Characters.
I  installed the outfit directly to the V4s body (with morphes injected) then I conformed it.. All of the clothing  morphes directly related to the outfit  (eg adj_SkirtL)seemed to work okay ,,But morphes such as Bulk,Glutesize,Hip Size, etc which were on panel did absolutely nothing.
This is typical of many of the products that I have purchased which leads me to beleive that it is common and not isolated to just a few vendors....
 
All of these morphes can be added using MorCloth and work well. 

So the vendors should remove these dials if there functionality does not exist....
