Boo's Astral Menagerie A-Z Inaccessible?

Hey all, Is there supposed to be a way to see Boo's Astral Menagerie from A-Z? At the moment, you can only see the monsters via CR block, which is not a great way to scrub through because there are monsters featured that are not new. Most books have the creatures laid out in several ways, and the A-Z leads me to believe this page isn't linked or is skipped over somehow, because it jumps right to "Astral Variants" when you click "Next Page". Am I missing something obvious? 

There is a mental disconnect because of how Roll20 organized the information compared to how the book did.  The "Introduction: Creatures A-Z" is a header that includes the sub-headers "Astral Variants", "Using a Stat Block", and "Astral Encounters". It is all one chapter.  The other three should be shifted to the right to indicate they are sub-headers.  So it should look like this:  Introduction: Creatures A-Z     Astral Variants     Using a Stat Block     Astral Encounters Go to "Using a Stat Block" to find the list of creatures. 

Thanks so much!
