Recurring Events don't carry over to next month in grid view

A church I help out from time to time uses this plugin on their website. It is a great plugin considering the functionality of the free version, and there have been no site-crashing issues since the recent major update, but the calendar grid does not display a recurring event from Dec 31 to Jan 1, while the list view displays it just fine.

The calendar is located at
https://lakeviewlutheranchurch.org/calendar/
and it links to their public church calendar at https://calendar.google.com/calendar/embed?src=lakeviewlutheranchurch@gmail.com.

The “OFFICE CLOSED” is what does not carry over from Dec to Jan, but you may see it in the list view on the side if you look at this before the year ends.

Thanks for taking the time to respond, and I appreciate the work you have put into this plugin.
