IBooks Author table of contents does recognize paragraph styles

Question

The video
https://www.youtube.com/watch?v=n2p08-NmqfQ
shows that using iBooks Author  I should be able to have text that is formatted with specific Paragraph Styles show automatically in the Table of Contents. But for me that does not work.  My version of ibooksAuthor is version 2.1.1 ( the latest) , under OS 10.9.1 (the latest) on an iMac.
The video shows the Inspector for TOC as a separate window and shows explicitly, under Sections, the items Copyright, Dedication, Foreword, Section and Section Text. It also has two Paragraph styles listed, Heading 1 and Heading 2. 
This set of TOC entries is  available for me with templates from Landscape with Portrait but NOT with templates of Portrait. The templates available for Portrait do not  list, in the TOC Inspector, Heading 1 or Heading 2.
Furthermore, the Portrait templates do NOT allow me to add any Paragraph style to the list (the control for adding Paragraph Styles to the list is grayed out), although the Landscape templates DO allow me to add any Paragraph style.
However, when, with a Landscape template (e.g. Basic) I format text as one of the paragraph styles Header 1, Header 2, Chapter, Section, it does NOT automatically show up in the TOC, though if I add a new section it does automatically show up. The TOC only lists Chapter and Section if these have been added from the menu bar.
When I use a Portrait template  (e.g. Basic or any other) and format text as one of the Paragraph Styles Chapter or Section that  text does not show up in the TOC. And the control for adding Paragraph Styles to the list is grayed out: I cannot add Header 1 or Header 2. The TOC only lists Chapter and Section if these have been added from the menu bar.
No matter what template I use, if I assign a paragraph style to some text, it does not show up in the TOC. And with Portrait templates, which is what I want to use,  I cannot adde any paragraph styles to the TOC Inspector in Portrait templates.

The iBA Help has info on: table of contents
Which includes:
Each book comes with a table of contents that is updated automatically. You can view the table of contents at any time by selecting Table of Contents in the sidebar. The table of contents includes a default set of items, but you can change which items appear. A table of contents can include:
Chapter and section titles: All chapter and section titles are included in the table of contents by default. If you remove a section from the table of contents, all other sections that use the same layout are removed as well.
Text that uses specified paragraph styles: By default, the table of contents includes all paragraphs in the book that use the Heading 1 and Heading 2 style, but you can include whichever styles you like. Paragraph styles appear in the table of contents only in portrait orientation. See Format text using styles.
The way the table of contents looks depends on the current page orientation. In landscape orientation (shown below), each chapter has its own contents page, with navigation buttons at the bottom. In portrait orientation, the entire book’s table of contents is visible as an expandable list.
Add or remove items in the table of contents
If the Document inspector isn’t open, click Inspector in the toolbar and click the Document Inspector button.
Click the TOC button.
Do either or both of the following:
To add an item: Click the Add pop-up menu , choose Add Paragraph Style, and choose an option from the submenu.
To remove an item: Select the item you want to remove and click the Delete button .
