Deleted Registrations still showing on facilitator confirmation email.

Registrations that have been deleted from a workshop are still showing up on the confirmation email that goes to facilitators as registered. A number of registrations were accidentally added to workshop ID15130 and then deleted. They're still on the facilitator confirmation email, but not the attendance register  -can you please fix - facilitators having a minor freak out thinking they have 30 people registered. Cheers :)
