It's been a few hours since I made the change, and now you're showing up as a bureaucrat in Special:ListUsers. Based on this I believe that the server takes some time to impose any changes in user rights. That means that when you made your changes back on Feb 27 and Mar 1, those changes probably didn't take effect right away, so perhaps you thought it wasn't doing anything.
