A family of Microsoft word processing software products for creating web, email, and print documents.
What has happened is that the hidden bookmark which Word inserts when you create a cross-reference has expanded to include a manual page break. You could recreate the cross-reference or replace the manual break with "Page break before" formatting (look in the Paragraph dialog box).
To avoid the problem in the future, never add content (text, a blank paragraph/Enter) at the beginning of a cross-referenced paragraph. Instead, add content at the end of the preceding paragraph.
