My guess is that there is a display override on the body. In the following image, you can see that the bottom body both in the graphics area and tree are following the part's display setting for HLR, but the top body is showing as shaded with edges. If you look in the Display Manager, an override has been applied to the top body. If I click on that shaded icon and choose "Default Display", then it will follow the part's display setting again.
I hope this helps,
Jim
