^That wouldn't explain it. The Compendium
does call her "Communications Officer Angela," but doesn't say anything about Kirk-J getting her name wrong.
I think it must just be a meme that got out into fandom. I could almost swear I remember a scene of Kirk-J calling her Lisa and having her say "Angela, sir," but that never happened. (It's probably a mutated memory of Yeoman Smith's one line in the second pilot, correcting Kirk after he called her Jones.)
