I am fixing someone else's code and I'm not familiar with Full calendar. Can anybody help me with full calendar. I have an event set for 7:00AM-7:15AM, it should show that on the UI. What happens right now is that whenever I set to 15 mins duration the UI only shows the start time e.g. 7:00AM but if I select 30 mins or higher it shows the full duration e.g. 7:00AM-7:30AM.

Here's snippet of the controller.js

        weekends: true,
        //eventBackgroundColor: component.get('v.eventBackgroundColor'),
        eventBorderColor: component.get('v.eventBorderColor'),
        eventTextColor: component.get('v.eventTextColor'),
        slotDuration: '00:15:00',
        slotLabelInterval: 15,
        slotLabelFormat: 'h:mm a',
        minTime: "7:00:00",
        maxTime: "20:15:00",
        timezone: "Australia/Melbourne",            
        views: {
            workWeekView: {
                type: 'agendaWeek',
                duration: {
                    days: 7
                },
                title: 'Apertura',
                columnFormat: 'dddd', // Format the day to only show like 'Monday'
                hiddenDays: [0, 6] // Hide Sunday and Saturday?
            }
        },
