Annual events (birthdays/anniversaries) are displayed monthly

[Srcodesalittle]

This is a relatively recent issue where events that should repeat annually are repeating monthly. It doesn't seem to be an issue with my google calendar since that only has the one instance per year.
Example image below, that person's birthday is on March 25th but it is displayed as if on the 25th of every month. Similar issues with anniversaries.

My config details are below

 module: "MMM-MyCalendar",
                position: "top_left",   // This can be any of the regions. Best results in left or right regio$
                config: {
                maximumEntries:6,
                maximumNumberOfDays: 60,
                fadePoint: 0.5,
                getRelative: 12,
                urgency: 2,
                showLocation: true,
                colored: true,
                coloredSymbolOnly: true,
                calendars: [
                        {//calendar1
                        url: '<.ics link>',
                        symbol: 'laugh-beam',
                        color: '#4DBD33',
                        },
                        {// calendar2
                        url: '<.ics link>',
                        symbol: 'grin-hearts',
                        color: '#FF69B4',
                        },
                        {// calendar3
                        url: '<.ics link>',
                        symbol: 'dna',
                        color: '#0276FD',
                        },
                                        ]

                                }

Can you please advise?
