When reviewing classes on the Home page, the All Present button is missing for a class scheduled to meet on the current date. The start/end times listed for the class are also incorrect. When selecting Attendance, Enter attendance using grid, the class is missing from the Class drop-down menu. The correct cycle day appears for the current date in the Calendar from Configuration, Academic Years, Session, Scheduling Calendar tab. In Scheduling, the class is scheduled to meet for the current cycle day. This only affects specific classes and cycle days.
