You are absolutely spot-on!
Unfortunately I don't have any clue where you can submit any errata items for this study guide. I can't find a link on the official page on the publisher's website. Maybe it is mentioned in the introductory pages of the study guide itself? In my humble opinion it would be a very big no-no for a certification exam study guide to have no errata submission form and an official errata overview. You can definitely post them here and we will comment on them, so you can clear your doubts about possible typoes/mistakes/errata in the study guide.
