Kristyn,
You must not have downloaded/installed the most recent update to AC 24? You'll note in the article that these setting are only part of build 40xx and above. From the Help menu, do a Check for Updates. If you do a Help > About Archicad it should show in the top left of the splash screen that you are on build 4018 if you are on the current update (as of today).
Any time you have issues, be sure you are running the most recent updates.
