Changes in text between different versions is nothing new. E.g. in "Kidnapped" by Robert Louis Stevenson, there are many changes, mostly made by the author. Including the age of the major character, who is 16, not 17, in early editions.
And then there's "The Hobbit" - a complete re-write of the end of the encounter with Gollum when "The Lord of the Rings" was taking shape.
You can enjoy the differences, or do your best to ignore them
