Purdue University allows for all day appointments, so their longest time span is 9 hours. However, there is one day where they open for 8 hours. Their hours are set up correctly for each day, but the "9 hours" option still displays on the 8-hour day, most likely from the Maximum Appointment Length setting. If the patron selects the "9 hours' option, there are no available appointment times to choose from in the Appointment Time field.
