I'm sorry for the confusion this is causing! If you open up the Style Attributes inspector and then select the first row in the document, what appears in the "All Level 1 Rows" or "Selected Row" sections?

More specific styles override more general ones; my guess is that either the Legal heading type is being overridden by another style in one of those categories, or that the Legal style has been applied in multiple places - that would "reset" the hierarchy. In either case, you can remove the unwanted style by clicking the small circle-with-an-X on the right side of the row in the S.A. inspector.

Does that help?
