Glitch or mistake while playing sims 4 with the WW mod

[BingusMcPain]

Hi, I don't know if this is a glitch or a mistake I made, whenever I use the mod, It glitches, the lower torso and the legs disappears, the autonomy settings doesn't appear too.
Please help? and also whenever I use the old version of the mod. the lower torso and legs are completely fine but they don't have private parts.. and still no autonomy settings.
