Dunning Wizard not printing default form

Running B1 2007 PL49. We modifed forms for each dunning letter and set the modified version as the default. We created a level for each letter, then, created a dunning term and assigned each letter. We assigned this term to all customers. We have double checked that the modfied letters are the defaults.

When we run the wizard, the system form prints out rather than our modified version. We created a new term, assigned the same letters, and ran the wizard again. This time no printing occured even though there were business partners with invoices in the results screen.

What are we missing that we can't get our custom letters to print?
