A notification appears if: 
    
You are scheduling the appointment outside working hours. You haven't assigned a staff member to the service. There’s another appointment booked at that time.   You can still go ahead with the booking; this is just to help prevent double bookings. If you’re booking a recurring session, any conflicts appear on the schedule summary page.

To schedule a similar session for the same client, select the relevant appointment on the calendar, then click Book Again. Fill in the appointment details to finalize the new booking.
