Cal.com acts as a hub and a point of coordination for your connected calendars. This means that Cal.com cross-references your calendars in order to understand when you are available for bookings. If you cancel an event that’s been added to your calendar, that will not automatically remove the appointment from the booking section of your Cal.com dashboard. If you want to ensure that bookings are removed, either cancel them by using the link provided in the confirmation or invite email. You can also cancel and reschedule meetings via the booking section of your account.
