Page groups do not display correctly
When page groups based on repeated text do not display as you expected in the Page
Group Navigator, you have not correctly selected or specified the text for the page
group.
You might need to adjust the width of the box that you drew or change the text that you specified.
If you selected the Begin page group when the selected text is found option, some characters in the PDF file might include white space that you need to enclose in the box you drew.
