That fact was, of course, a case of the writers taking liberties with facts (or being just plain careless) rather than a case of time traveling changing history. One could even blame it on whoever was responsible for the end credits, since the name "Malcolm" doesn't surface in the actual filmed episode, but only printed in the credits. These would be the same people who misspelled one of the regular cast's name through a number of early episodes: Whit Bissell's name was listed as "Whit Bissel" in four or five episodes after the pilot.
