Inventor 18 drawing not displaying everything, but model DOES

I have a drawing.

I bring in my model, which has everything ON. Looks the way I want it. Then in the drawing, some parts are OFF.

The visibility box is solid for files in question. I check it and the files comes on.

One particular file though after I check it.......makes the whole thing disappear!

The program has the current updates, etc.

Fuel tank.

Surface Bodies in question.

Solids come through. Surfaces don't show in drawing. Surface were translucent to start with.
