Why is the Appointments List red? A "Problem Appointment" occurs when a registration is placed on hold because it no longer fits the current event configuration. When this happens, a red exclamation mark (!) will appear next to the Appointments List section on the sidebar, and the specific entry will be highlighted in red . Common Causes Problem appointments are typically created when changes are made to the schedule after bookings have already occurred. For example: Deleted Slots: If you remove a time slot that already had a participant registered, the appointment is not automatically deleted. Instead, it is flagged as a "Problem" for you to resolve. Resource Changes: Modifying teacher availability or roster limits while the scheduler is live can sometimes trigger these alerts. Conflicting Admin Actions: A problem is triggered if an administrator (or teacher) manually books an appointment for a parent who has already successfully booked a slot themselves. How to Resolve When you see a red exclamation mark in the sidebar: Click on the Appointments List tab. Locate the rows highlighted in red . Decide the Action: You must manually choose to either delete the appointment, move the participant to a new available slot, or "Confirm" the slot to clear the flag.
