Have you tried going to the menu on the upper "tool bar" that says figure (Between edit and object) and making sure genitals is checked? I am kinda confused to which menu you are refering to in your post. Are you talking about that one or the figure library menu? My P4 males always load up sans crotch when I bring them into a scene, and I have to go into the tool bar at the top to get them to show up.
