sorry for the late response! if i remember correctly, shinra's face expression animations use ALL of her blendshapes, including the morphing ones that change how her face is structured. because of this, the changes you make in edit mode will be overridden by the default face animation in play mode. basically, you'll either have to remove her face expressions from her FX layer and make your own, or go into her existing ones and change the blendshapes to what you want them to be for each expression. i hope that helps!
