Miette's BODY is a MOR pose, it is NOT an injection pose. Miette's head morph is NOT injected in the MOR pose for the body. That is why it is called MietteBody_MOR and not MietteBody_INJ. A MOR pose is simply a set of dial parameters for the Aiko body morphs. The Realistic morph is not disabled in the MOR pose because it is not necessary. It is only necessary when Miette's head morph is actually INJected. When this happens, the body to head JCM control is disabled to prevent the body MOR pose which contains Realsitic set to 1.000 from changing the head realistic morph. 

You must apply BOTH the head and the body pose to get the full figure for Miette. Alternately you may apply the Head INJ only and use the custom morph target with the default Aiko body. If you use the body only MOR pose file, you will get the body only and the Realistic morph will be applied to the head just as Poser and DAZ intended. In order to disable the Realistic morph from the head, you must apply the Head injection pose.
