Format error in checkout

Since updating to 3.7.1 I’m getting a formatting error in the woo checkout page due to the changes made to mep_extra_price.php.

The following line is the cause:
$item_data[] = array('key' => __('Details Information','mage-eventpress'), 'value' => ob_get_clean());

I think you need a line break at the start of the output, this fixes the problem for me but you may find a better way.

$start_time                 = get_post_meta($eid, 'event_start_time', true);
echo "&nbsp;<ul class='event-custom-price'>";

I had to use ” ” rather than <br> or ” ” or “/n” as these didn’t work.
