How do I get rid of the duplicate product details?

	<div id="hikashop_product_description_main_mini" class="hikashop_product_description_main_mini">
		<?php
		$resume = substr(strip_tags(preg_replace('#<hr *id="system-readmore" */>#i','',$this->element->product_description)),0,300);
		$resume .= "...<a href='#description'>See more</a>";
		echo JHTML::_('content.prepare',$resume);
		?>
	</div>
