Extra sliders like height come from the RaceMenuPlugin.esp, make sure you are using that one in addition to the RaceMenu.esp. Height should work fine. The only features not enabled are head mesh import, sculpting, and body/feet/hands overlays, all due to the changes Beth made to meshes taking away Expired's hack he was using to make it work. Sculpting and head mesh import can be bypassed by using Oldrim, exporting the preset and importing that preset in SE, since presets work fine and import the sculpts.
