Since the Amazon techs couldn't fix the glitch with the Amazon UK website on The Sentinels' Mother page, I've taken down the page and published a new one that should be free of any errors.

I'm super sorry for this really long and drawn out problem!
I really didn't understand why the complete book was sent to everyone else in the rest of the world except for Europe. But anyway, thank you for being patient and waiting until the problem got fixed.
