Same problem in Global Redmi note 4 (mido)Mi 5s 3/64GB
I have a problem with the calendar. The "you-have-an-appointment-dots" showing the days you have an appointment are created one week after your appointment. So you get confused.
I uploaded screenshots. The appointment created for 18th July doesn't show a dot - it appears on 25th July - where I don't have an appointment.
