I 
  have added the header 'Election title' to the attached election, linking it to 
  races 10 and 20.  I generate ballot artwork, but the header does not 
  appear on the ballot, irrespective of whether I force relayout in the Header 
  Editor or not.  When I reset artwork, then generate artwork, the header 
  appears on the ballot.
   
  Why 
  should I have to reset artwork in this case to make the header appear on the 
  ballot?   What am I missing?
