Header Data using Style Sheet

I have created a Style Sheet using the StyleSheet Tool in Word. In my document i am using Merge data from a Sales Quote in the “header” of the document. When the document is created from the Quote the data appears properly on my screen in the header, however, when I print the page the quote data disappears and the text for the merge data field is displayed instead.

The Merge Data in the body of the document is unchanged and works properly. It’s only the merge data in the header. Any thoughts?
