Usually when you create a new morph it shows up in the Body actor, in the Morph category, automatically. You'll need to drag and drop it into the parameter dials folder that you want it to "live" in BEFORE you save your injection pose.

Individual body part morphs often don't get arranged the same as those in the Body actor.  Whether or not you want to arrange all of those the same, or just keep them as they are, is up to you. I think most people use them from the Body actor (for body morphs) or from the Head actor (for face morphs) anyway.
