The thing to remember about section breaks is that they display of the type of section that follows the section break, while they store the section type (and all other properties) of the section preceding the break. The properties of the very last section is stored in the final paragraph mark of the document.

If you display the Page Setup dialog box for a section and click OK to confirm the settings, you should be able to use F4 to duplicate those settings for another section.

However, in this particular case, simply changing the type of section, as Andrew suggested, might help.

For "everything" on sections, have a look at Working with sections.
