Aggregate Rating Displayed On Posts Page

WordPress 4.3.1 running Dynamik-Gen theme. The website is not live yet so I can’t send links.

I am totally new to PHP code and working things that were already in place. I have created a custom post type called “listings” and have used the [WPCR_INSERT] with a lot of display:none CSS to get only the stars displaying in each listing block on the multiple listing page. The listings are displayed on the page via shortcode which has been setup in the custom-functions file. Here is the HTML output portion of that shortcode:

$listings_html .= '
	<div class="listingpost">
		<div class="listingimage">
			<a href="'.get_post_permalink($listing->ID).'" title="'.get_the_title($listing->ID).'" target="_blank" rel="nofollow"><img src="'.$featured_image_url.'" alt="'.get_the_title($listing->ID).'" class="size-full" /></a>
		</div>
		<div class="listinginfo">
			<h5><a href="'.get_post_permalink($listing->ID).'" title="'.get_the_title($listing->ID).'" target="_blank" rel="nofollow">'.get_the_title($listing->ID).'</a></h5>
			<span class="featureaddress">'.get_field('address', $listing->ID).', '.get_field('city', $listing->ID).'</span>
			<br />
			<br />
			<span class="listingcontent">'.get_the_content('<br /><br />Find Out More...').'</span>
		</div>
		<div class="reviewteaser">
			'.do_shortcode('[WPCR_INSERT]').'
		</div>
		<div class="reviewlink">
			<a href="'.get_post_permalink($listing->ID).'#reviewanchor" title="'.get_the_title($listing->ID).'" target="_blank" rel="nofollow">Leave A Review</a>
		</div>
		<div class="googlemaplink">
			<a href="'.get_post_permalink($listing->ID).'#mapanchor" title="'.get_the_title($listing->ID).'" target="_blank" rel="nofollow">Show Map</a>
		</div>
		<div class="videolink">
			<a href="'.get_post_permalink($listing->ID).'#videoanchor" title="'.get_the_title($listing->ID).'" target="_blank" rel="nofollow">Play Video<i class="fa fa-youtube-play"></i></a>
		</div>
	</div>

The problem is that the stars are not showing the aggregate sum from the individual listings. They are showing the default rating from 0 reviews. Every listing has reviews that are displaying correctly on the single listing pages.

If anyone has any ideas on which way to turn, I would be forever grateful!
