Apps are not showing up with parental controls

I recently purchased Spellboard from the Mac App Store to help my son with his spelling quizes. I have parental controls set up for him and the app does not show up in his applications folder. I have it selected in parental controls, the app is rated for 4+ and I have the permissions set to 12+. The app shows up and works fine under mine and my wifes logins which are set to admin. I can't figure this out. Any other applications we select that ARE NOT Mac app store purchased show up fine when selected for him. Anyone else run into this problem? Any fix?
