Where are all the sections?

Hello,

I’m a little confused. I found the “Sections order” panel which looks great. Easy to drag and drop and reorder. But as I looked more I got confused. That panel has 13 different sections, but my book page has just 8. Some I cannot find at all.

For example, there is a video sample section that I am curious about because we have video trailers. But I can’t find the settings for that data anywhere. The same goes for About the Author

And I’d really like to add some reviews or use that section to feed from somewhere else – but I can’t find that section either.

Also, when I tried moving the Buy Books section up, my Order Now buttons didn’t move any higher.

Can you help me to understand what’s going on? Also – it would be really helpful if the sections in the “sections order” box actually matched the sections of the book page.
