Yes, you are partially right.
In the published version there's still the old mistake that has already been corrected, please see this post:
On the other hand, you should read the whole thread before reporting an error.
But you are right in another way: it's time for a new edition of book 1, where many corrections have been made now.
I'll ask Prof. Delcamp.
Thank you for your diligence - it's still better to report an error twice than not at all.
