Excuse me, but why don't you go to Wookieepedia, correct it and argue that they were wrong all along?You could argue that Revan and Malak were not their real names, but if that's the case, you could just as well argue that for almost all other characters who have only one name. How do we know that Atris, Kavar, Juhani, Palpatine, Dooku etc. were real names and not nicknames? We have no more reason to presume so beyond those for Revan and Malak.
