Sometimes events may appear multiple times on a calendar view, such as if the user and one of their children are both affected by the event.
If an event exists on both user’s ‘My’ calendar and school-wide calendar, the event will only show a single time with the color of the first calendar that appears on the list of calendars.
Similarly, if an event appears on more than one school-wide calendar, it will appear for a user only a single time with the color of the first calendar in the list. As calendars are selected and deselected, the color of the event may change to match the specific calendar.
