header settings for section are set with same content on left and right pages, and same content on first page unchecked. While left and right works correctly, the first page option is buggy. When new section is first made, the header appears regardless of how checked, and any changes affects all the right page headers. UNTIL I close the document and reopen it. Going back in after the fact runs the risk of my missing a correction, and closing and reopening after every chapter is time consuming. It is the only fix at the moment.
