Thank you for your keen eye, Andy. I’ve modified this one as it is a clear oversight from my part indeed.
As for the second edit you mention, I have decided to keep it as I don’t see it as a mistake per se, but just that the sentence could have been written in a clearer way. Since many people have highlighted it and editing it would make their highlight disappear, I prefer keeping it as is.
Thank you also for your comment and kind words of course!
