Revit :: Walls Hiding Fixtures When Plan Printed

I have some Plumbing "Fixtures" that aren't showing up when the plan is printed. In the view they are visible, but in the print they disappear as if to be covered up by the wall. Unless the "Fixture" is slightly outside of the wall then it will show up. What could be causing this? The fixtures that we're using are simply model lines that form a circle since they're only there to hold a place in a schedule for its info.

So as you can see the dots are visible but when I go to print they disappear...
