You are using the Jive Solutions Advanced Navigation (formerly known as Mega Menu) Add-On. When you insert a Table of Contents (ToC) into a piece of content, and someone uses one of the ToC links to reach a section, the top line (section header) of the document is obscured by the menu.
This was a bug in the Advanced Navigation Add-On and was fixed by Professional Services in the Advanced Navigation Add-On release number 1.2.1.
- You can get the latest version from Professional Services.
- You can refer to the configuration guide for assistance in installing and configuring.
