Description of problem:
According the User Guide, item "4.4 Exporting a Process" [1], when you export in PDF format the Process' documentation values should be included. 

   "... Note that when exporting to PDF, the output PDF file will contain also the values of the Documentation properties of the Process and its elements." [1]

The PDF generated contains only the Process diagram. The documentation values/properties are not included/printed in the PDF.
