Next Event Countdown Not Displaying Seconds

We have inserted the Events+ "Next Events Countdown into our child theme. The countdown displays on the homepage fine EXCEPT that the "seconds" are missing. I believe I have the code entered properly into our home.php layout.

<div class="counter">
<?php echo do_shortcode( '[next_event_countdown title="yes" format="dHMS" expired="Thank You For Your Support"]'); ?>

What is missing?

Please help. Thanks!
