Hi,
This actual thread have more than a year ; it means that the code is working for more than one year and I don't see why you wouldn't have these fields unless you have an override for the "preload" part of the email.
Please check that you do not have an override for the preload and please provide more details about your current website and current status.

By the way, do not send me private message, use the "contact us" form instead.
