Creating Help Center sub-categories

Creating Help Center sub-categories

Does anyone know how to create sub-categories in the Help Center?

In the manual it states -

To create a new section, do the following:

  1. In the Help Center home page, hover your mouse over a Category <Name> located on the left pane.
  2. Click the Gear icon and then click the Plus sign.
  3. Provide a name for the new section and click Save.
    You can click the Pen icon to rename the section if required.
However, when I 'hover' over a Category, there is no Gear icon.????
