Mike,
Show me your clear settings. Move your mouse pointer to the "Clear" button and then hold down the Shift key on your keyboard. The button will change to "Settings". Click on it while you continue to hold down the Shift key. You will then get the "Clear Settings" dialog. Look for the "Creator's Identity" field in the list. Are the check boxes checked?
Mine are, and that field is cleared (and its Apply check box) when I click the Clear button.
HTH,
