Hi everyone, this is my first post on this forum.

There are two listings of MCTB for Kindle on Amazon and both seem to be the 2nd edition according to their titles but have several major differences.

1. https://www.amazon.com/Mastering-Core-Teachings-Buddha-Unusually-ebook/dp/B005TQU7P8/
2. https://www.amazon.com/Mastering-Core-Teachings-Buddha-Unusually-ebook/dp/B079LW4J8K/

Which one of these is the 2nd "Revised and Expanded" edition?

Judging by the covers #2 seems to be MCTB2, but #1 has more pages and was published more recently than #2

Also, if you open #1 in the Kindle app the cover switches from orange to the purple one of #2 (see attached images)

Could anyone please kindly clarify this for me, thank you!

Yes, it's confusing. It should be the one with 1017 pages.
