Changing names within Family Safety

We've been using our PC for ages with only one user account, but in an effort to sort out the parental controls at last we created another account, made it the administrative account and turned the old one into a standard account for the kids to use.  In the process we changed the account names and none of them now have my name.  So in the Control Panel/User Accounts and Family Safety/Parental Controls window the accounts have the correct names.  Then we downloaded Family Safety, but this insists on calling all the accounts by my name which makes things very confusing!  Is there a way of teaching it the new names?
