I noticed the zip code and vendor phone number are on the same line which could be a bit confusing.
For some reason in the shopfunctions for renderVendorAddress it ignores the line seperator for zip code? (possible assuming it is always last field?)
if ($field['name'] != 'title' and $field['name'] != 'first_name' and $field['name'] != 'middle_name' and $field['name'] != 'zip') {
Also just noticed same thing on the customers billto and shipto address?
in mail_html_shopperaddresses.php
<?php if ($field['name'] != 'title' and $field['name'] != 'first_name' and $field['name'] != 'middle_name' and $field['name'] != 'zip') { ?>
<br class="clear" />
<?php
}
