Custom Fields in PDF outputs

Custom Fields in PDF outputs

I created a couple of custom fields.  e.g Country of Origin and HS Tariff Code.  I need these to appear on a clone of a sales order PDF template but on on the standard PDF template.  When I select "appear on PDFs' it appears on both but when I don't select it appears on none.  How can I have a custom field appear only one of the pdf templates.
