Sheet Wizard Blank Title 74941

On the Sales Order Entry screen, I am trying to add a tab to the
Header...Comments tab. When I go to the Wizards...Sheet Wizard, there
are 2 commentsPanel1, but they are both for the Lines Comments. I
cannot add a tab to the Header Comments, I can to the Lines...Comments
tab. How do I add a tab to the Header...Comments tab? The version of
Vantage that we are running is Vantage 8.03.407. Any help is
appreciated.
