Drupal 6.22, Signup 6.x-1.0, CCK 6.x-2.9, Date 6.x-2.8.

I'm trying to put date tokens for my date field into the confirmation emails, but they do not appear. If the email configuration is:

Thank you, [user-name], for signing up for [title].

The date of this event is:
[field_clinic_date-mon] [field_clinic_date-dd], [field_clinic_date-yyyy] from [field_clinic_date-time] to [field_clinic_date--to-time]

You will get a reminder email 1 day before the event.

If you need to cancel your signup, first log in to the site with your user account, and then use this URL:
[signup-cancel-url]

The resulting email contains:

Thank you, memcinto, for signing up for Children's Clinic: Sickle Cell,
December 21, 2012.

You will get a reminder email 1 day before the event.

If you need to cancel your signup, first log in to the site with your user
