Text shows but drawn Lines don't show in PDF

I have a silk-screen file for a sheet metal part.  I have a DXF layer that came in from Solidworks and few other layers that I have Visibility and Print OFF. 

I also have a Crop Marks layer, a Silk-screen Lines layer and Silk-screen Text layer.  On those layers I have Visibility and Print set to ON when I use File>Publish to PDF.

But when I look at the PDF that it created I don't see the lines or crop marks.

Here's the file
