Thanks for your help jcl! Unfortunately that did not work, I attach the screenshots. I did as you told me, I deleted the ebook from Kindle -and even the fragment of the third edition that I had sent hoping to get the full version- and send the ebook from Amazon to Kindle, it downloaded, the cover shows third edition (screenshot3) but when i open it the cover is not from the third edition and the copyright shows it is from 2017 and chapter 7 isn't 'in the 5th dimension' (screenshots 4, 5 and 6 respectively) . It is strange the cover in Kindle before opening says third edition as well as in the Content and Management section of Amazon website (screenshot2), like it is halfway there...Maybe you can check with Amazon or should I contact their support?
