Contempo Real Estate Custom Posts update not working

My first attempt in updating this plugin resulted in losing all listings, like the other poster in this forum. I reverted back and tried again and now, the listings are back and the new listings categories show up (country and community, is there a third?), however in the admin for listings, while it says I have 61 listings over 4 pages, only the first listing shows up on each page. The rest of the page is blank. I see the same error in my logs as the other post here:

PHP Fatal error: Call to undefined function ct_listing_price() in /wp-content/plugins/contempo-real-estate-custom-posts/includes/ct-real-estate-custom-post-types.php on line 179
