Admin UI Why is the Appointments List red? This indicates appointments with an unresolved problem needing attention — the tab and the appointment both display in red. See the  Problem Appointments  page for the different ways this can happen. I see orange appointments labeled "Customer is creating this appointment" — what do I need to fix? Nothing — this is expected behavior. Orange indicates a booking  in progress : These appointments can't be manually deleted or selected for email notifications. If the participant goes inactive without finishing, the system automatically cancels the in-progress booking. The orange status disappears once the participant completes booking. This also helps admins booking manually — it prevents you from selecting a slot a participant is actively booking. Why does changing "Open scheduler to customers" on one event also change it on my other events? Your events are linked via  Propagator Mode . To make changes apply to only the current event: Go to  Events Preview / Events Settings . Under  Propagator Mode / Propagate Changes To , change the setting from  "all events of this type"  to  "only the current event."
