Why do I have duplicate HTML pages in the same book? - On Premises 6.4

FAQs - On Premises

While a topic may appear in the same Book multiple times, when published a separate page is created for each occurrence. This is because such things as the page-to-page navigation (next/previous topic) and the "see also" and "in this section" related topic groups vary according to where the topic is placed in the book. While the topic content is the same in each instance, the navigation is not.
