Body parts do not appear in view when checked

How come I have some parts visible in the camera view and others parts not?

I have everything checked

From head to shoes I have the head missing and left arm. every other body part shows but these on one character.

on another character the entire lower body does not appear. Why is this so?

body parts are still missing. does anyone have any thoughts?

Does this happens when rendered? Are you using 3d layers?
Did you convert those files to your library and then drag then back to a different comp?

Are the drawings exposed on that frame? Are they in the camera view? In other words, could they be off to the side, or scaled really large or really small?

In the drawing view, if you turn on the drawing grid, are they on the grid?
