First, you need to select the girl, enter the tab 'Female Morphs'.
Second, find the dropdown by the name 'Morph & Pose' to the right of 'Show', change it to 'Pose'. Check the 'Only Active' option besides it. Then you have all the pose morphs working right now showing down below.
Third, zero the morphs that affect the expression. I used only a couple of expression morphs, so it won't be too hard to get rid of them.
