OS X :: Always Allow In Parental Controls - How To Reverse

I have my daughter's accounts setup with parental controls (she's 9). I use the Parental Controls to limit the apps that she has access to so she does not get into trouble with applications that she should not be using.

I was working in my daughter's accounts the other day and I accessed the "System Preferences" application. Because this was one of the applications that I blocked, I was prompted (something to the effect of): This application is blocked by parental controls do you want to "Always Allow access", "Allow Access One Time", "Cancel"

I selected "Always allow" by accident. Now, when I go into parental controls, the "System Preferences" box is still unchecked, indicating that it should not be accessible by my daughter - but, when I go into my daughter's account, she has free/clear access to system preferences. I've tried checking and unchecking the Systems Preferences in parental controls, but it does not block access.
