Including WBS in Visual Reports in MS Project 2007

I’m trying to generate a Visual Report in MS Project (through Reports –> Visual Reports –> Budget Work Report) that will show me budgeted work by WBS by month. Even though I can click on “Edit Template” and see that “WBS” has been included in the Selected Fields list, the Excel and Visio reports that it generates don’t seem to include the WBS field.

Does anybody know how to make it include WBS?

Thanks so much.
