The problem is super conforming. If a piece of clothing is super conforming and you conform it to a figure you can no longer adjust the clothing using the FBM dials. What is happening is that you change the value and then poser ignores it and uses the settings of the base figure instead.

You can test this by loading the clothing all by itself and test the FBM without loading a figure. If they work when you only have the clothing loaded then your problem is with super conforming.

I personally hate super conforming because it makes it a pain to adjust the morph settings.
