This is broken for me too.
This is the load order I was trying to use:
mods/JUICED - Credits
mods/JUICED - Fixed Moon Skybox
mods/JUICED - Chunk Fixes
mods/JUICED - FPS Camera
mods/JUICED - Strings
mods/JUICED - Lua Libraries
mods/JUICED - Shaders
mods/JUICED - Animations
mods/JUICED - Textures
mods
mods/M2M
mods/Humanistic Sliders Evolution
mods/Open City
mods/ReFabricated
mods/Cutscene Patch
mods/HQRadioN69
mods/SR2 Shadows mod v1
mods/GotR/Optional
mods/GotR
This video shows what happens to me when I go to the Customization menu with that load order.
I did experiment with load order, and loading Humanistic Sliders Evolution before M2M *did* change the menu and the options that appear, like "Age" vanished and more options appeared.
But its still broken.
