i just had this problem as well.
i changed line 2375 of the-events-calendar.php to this and it seems to work
2375: //$this->date = str_replace( substr( $date, 8 ), ’01’, $date );
2376: $this->date = $date;
now this will break again in an update, but hopefully my email to the devs will get integrated and the fix will be in the newer version
