Description:
I have created a report template in Writer, that has values inserted from a data base query. The mail merge function works fine in the body of the document. If the data base field is in the header, the merged document shows the field, but not the value of the Query. 

Steps to Reproduce:
1.Create a database with a query.
2.Insert the fields of the query in the header of the document
3.Run a Mail Merge

Actual Results:
Fields in the header displays the field, not the values of the query.

Reproducible: Always
