I fixed your top bar.

Here is the fixed top bar insert for you.

I made it check if the field was empty first.. I also made it not do esc_html for the phone field so that I could make it a clickable link for mobile devices.

<?php
	//Getting Customization data
	$phone_field 	= get_theme_mod('phone_field', 			'123-123-1234');
	$small_address 	= get_theme_mod('small_address_field', 	'248 Texas , 43539');
	$time_table    	= get_theme_mod('timetable_field', 		'Monday - Friday : 09:00-17:00');
?>
<div class="medium-6 small-12 columns text-center text-medium-right">
	<?php
	if (!empty($phone_field)){ ?>
    <div class="action-box">
        <p><i class="fa fa-mobile" aria-hidden="true"></i> <?php echo $phone_field; ?></p>
    </div><!-- icon box ends -->
	<?php }
if (!empty($small_address)) { ?>
    <div class="action-box">
        <p><i class="fa fa-map-marker" aria-hidden="true"></i> <?php echo esc_html($small_address); ?></p>
    </div><!-- icon box ends -->
	<?php }
if (!empty($time_table)) { ?>
    <div class="action-box">
        <p><i class="fa fa-clock-o" aria-hidden="true"></i> <?php echo esc_html($time_table); ?></p>
    </div><!-- icon box ends -->
<?php } ?>
</div> <!-- Third Column -->

That's great i will consider implement this in future release. Thanks :)
