I'm not really sure I understand correctly. What is wrong ? The English translation ? Well, usually we have to read what the author wrote, even if he made a mistake. Is it a small mistake, like a typo, then we can usually correct it, because it's probably just an error. But if the entire sentence is different, then maybe it was the author's interpretation and then we are not allowed to edit or censure it. Unless you find another copy where it's different, then we can probably blame Gutenberg that they made a mistake in the transcription.
