You can remove flow heading changes you have assigned to individual pages and return them to using the Default flow heading.
Any pages whose flow heading has been changed are shown with a yellow marking along their bottom edge, or along their bottom and left edges, in the Pages section of the Pages panel.
Prerequisite
The right zone is shown.
Procedure
Result
All flow heading changes are removed from either the selected pages or from all pages in the layout currently open in the music area. Pages return to using the Default flow heading in the page template set applied to the layout.
If you removed flow heading changes from selected pages only, any other pages with flow heading changes in the layout are unaffected.
