I did it via the Password link in the username dropdown menu as Test Account and under the User Essentials tab in the admin control panel as Amaury. Could it be because Test Account doesn't have an email?
You may have an add-on that is preventing it from updating at all. In theory, anything you have which may extend the User DataWriter that doesn't extend it properly may prevent the change logs from logging at all, or logging correctly.
For both of you if the issues persist then you should try it again with all add-ons disabled.
