WD: Different Odd and Even Header/Footer Affects All Sections

If you are working in a multi-section document in Microsoft Word and you select Different Odd and Even Pages in the Header/Footer dialog box for one section and then edit an even header or footer, Word adds an even header and footer to all other sections. In previous sections, blank headers and footers exist on each even page. In subsequent sections, the even header or footer from the modified section is repeated throughout all subsequent sections.

Different Odd and Even Pages for Headers and Footers are document-specific settings. Making this setting in any section of a document will affect the entire document.

Word, by design, will put any header or footer already typed into the Odd Header or Odd Footer.
