Multi-Page Documentation is not working

The multi-page documentation for RHEL v7 release notes is not showing all the information, unlike single-page or pdf formats. For example for the chapter 9 "Clustering" in multi-page format you don't see the chapter "9.2. Keepalived and HAProxy Replace Piranha as Load Balancer" neither 9.3 or 9.4. The same happens for all the chapters of the release notes documentation.
