Events+ plugin not displaying shortcode correctly

On the Page there is a Events+ shortcode that was displaying events for this month in a calendar format. After an update, this has stopped displaying correctly. It is not displaying the year 4400 and does not show any events. I have checked the installations time and date and it all seems to be correct. All events seem to be loaded correctly in the portal and are individually accessible. Shortcode used and previously working is [eab_calendar with_thumbnail="yes" navigation="yes"]
