When you change the page orientation or paper size in one of the sections of a document, a continuous section break becomes a next-page section break. This change is not reversed if you reverse the page orientation change.
This behavior is by design. In Microsoft Word, you can change the page orientation of one or more sections within the same document.
If you insert a continuous section break between sections that are subsequently formatted for different page orientations or paper sizes (for example, landscape and portrait), the continuous section break becomes a next-page section break. This occurs because a single page cannot contain both portrait and landscape orientation. Each page can contain one orientation only.
If you later change the sections of the document back to the original orientation or paper size, the continuous section break is not restored. The next-page section break remains until you manually change it back to a continuous section break.
To restore the section break, you must set the page orientation for adjacent pages to be the same, either portrait or landscape. Then you can change the section break back to a continuous section break:
With the insertion point positioned in the second section, on the File menu, click Page Setup. On the Paper Size tab, change the orientation to match the orientation of the previous section. For example, either Portrait or Landscape.
With the insertion point positioned in the second section, on the File menu, click Page Setup. On the Layout tab, click to select Continuous in the Section start portion of the dialog box.
