I have a custom module position which I have added to my template, it appears in the 'styles' layout section of the template configuration and it appears when I preview positions with ?tp=1. When I assign a module to the position, it is visible when in preview mode (?tp=1) but not when I view the site as normal.

Is there something I have missed? I have added the position as per the documentation (http://www.t3-framework.org/documentation/bs3-layout-system#add-position) including updating the templatedetails.xml file.

For reference, this is what I have added, in its context. It is the 'center-block' position which is new.

		<div id="t3-content" class="t3-content col-xs-12 col-md-6  col-md-push-3">



          <?php if ($this->countModules('center-block')) : ?>

          <jdoc:include type="modules" name="<?php $this->_p('center-block') ?>" style="T3Xhtml" />

		  <?php endif ?>	

          

			<?php if($this->hasMessage()) : ?>

			<jdoc:include type="message" />

			<?php endif ?>

			<jdoc:include type="component" />

		</div>

The development site page I am working on is here with a dummy module in the new position:
