Registration email custom language string

I have recently upgraded to 3.8 and the new registration system with deadlines and user cancellation works really well.
I had a custom language string for the confirmation email that is sent after enrollment. The change from default was to display the [CONTACTEMAIL] (set for the event) instead of the [AUTHOREMAIL].

However, the [CONTACTEMAIL] does not seem to work any more.
The language string now invokes the =11.0pt[STRING_CANCELLATION] that includes this author mail.
I have tried to use a language override with contact [CONTACTMAIL], however this does not work ([CONTACTMAIL] is not substituted by the actual contact's mail)
How can I set this mail to be the contact email that is set for the event instead of the mail of the person who made the event?

This is the language string I use:

Hallo [NAME],\n\nU heeft zich aangemeld voor evenement '[TITLE]'.\n\nAls u de details van dit evenement opnieuw wilt zien, selecteer dan de volgende link of kopieer en plak deze in uw browser:\n[EVENTURL]\n\nDeze e-mail bevat uw persoonlijke gegevens die zijn ingevoerd bij het registreren voor dit evenement op de website [SITEURL].\n\n[STRING_NAME][STRING_EMAIL][STRING_PHONE][STRING_TICKETS][DATES_REGISTERED_LIST][CUSTOMFIELDS][STRING_NOTES]\nU kunt informatie opvragen, uw persoonlijke gegevens wijzigen of uw registratie annuleren door een e-mail te sturen naar: [CONTACTMAIL]\n\nMet vriendelijke groet,\n[SITENAME]

All tags get replaced, except for CONTACTEMAIL

PS is there also a tag for the cancellation link, since I would love to add this to the mail as well.

That worked. E was missing. Thanks for your help.

Is there a tag for the cancellation link as well?

I mean a tag that will display the cancellation link. Since I don't want to include the email of the author in the mail, but the email that is set as a contact, I cannot use these "standard" cancellation strings.

To clarify:
Wat i would l like is a tag like [CONTACTEMAIL] that displays set contact email for the  cancellation link like: [CANCELLATIONLINKTAG] --> displays cancellation link.
 

Hello,
It seems we do not quite understand each other.
What you describe is how I have set it up right know. However this does not include the option of displaying the cancellation link in the email.

Default option (cancellation_string)
contact authoremail or click on cancellationlink to cancel registration

What I want to accomplish:
Contact contactemail or click on cancellationlink to cancel registration

What I can do now (deleting [STRING_CANCELLATION] and replacing this with: Contact [CONTACTEMAIL] to cancel registration)
Contact contactemail to cancel registration.

IMHO there are 2 options to accomplish what i want:
1. a tag that can display the cancellation link. Then I can replace [STRING CANCELLATION] with "Contact [CONTACTEMAIL] or click on [CANCELLATIONLINK] to cancel registration"
2. Have the option to edit the [STRING_CANCELLATION] to use the contact email instead of the author email if set for the event.
