You'll need to edit the index.php of the Coolness and MyCommunity template and manually change it as they are our older templates and do not have the parameter usage implemented for the copyright display. You can find it at the bottom of the templates index.php file exampled as follows.
Code:
<div id="copyright">Copyright © <?php echo date( 'Y' ); ?>, <a href="http://www.joomlapolis.com/" target="_blank">Joomlapolis.com</a>. All Rights Reserved.</div>
MyCommunity: templates/mycommunity/index.php
Coolness: templates/coolness/index.php
