I am using the default calendar module to show events and birthdays. For this it links to a google calendar. In this calendar I record the events and birthdays on the day they started and repeat them annually. When I record more than three events/birthdays in the calendar the module stops showing any information from this calendar. My config looks like this:

	{
		module: "calendar",
		header: "Festivities",
		position: "top_left",
		config: {
			timeFormat: "absolute",
			maximumEntries: '10',
			maxTitleLength: '20',
			displayRepeatingCountTitle: 'true',
			calendars: [
				{
					symbol: "birthday-cake",
					repeatingCountTitle: "jaar",
					url: "https://calendar.google.com/calendar/ical/1egmps6ppemii2f82svtu4nbfg%40group.calendar.google.com/private-ab0550be85d14d2a20c24c4eebd4e97e/basic.ics",
				},
				{
					symbol: "flag",
					repeatingCountTitle: "jaar",
					url: "https://calendar.google.com/calendar/ical/e805v9vdbqh12san27amedqlt0%40group.calendar.google.com/private-8b974556875b59299eeccfa118c1872d/basic.ics",
				},
				{
					symbol: "flag",
					url: "https://calendar.google.com/calendar/ical/nl.dutch%23holiday%40group.v.calendar.google.com/public/basic.ics",
				},
			],
		}
	},

For debugging I created two calendars the first has three events the second has the same events including a fourth one. You can check this with curl -L . The information in the calendars is fake and only there for debugging purposes. The calendars will be deleted when the issue is fixed so feel free to use them for debugging.

Can somebody let me know what I am doing wrong or check if there is something in the module code that explains this behaviour. Thank you.
