Unintended blank pages often arise from misplaced section breaks. To eliminate these, first ensure that the section break is necessary for your layout. If a section break is placed at the end of a page, try moving your cursor to the beginning of the blank page, then deleting any unnecessary space or breaks. If adjusting section breaks doesn't resolve the issue, double-check your document's paragraph formatting—hidden formatting options like page breaks might also contribute to unintended blank pages.
