problem with WP-Post Ratings meta content

hello
i use WP-Post Ratings for my site and all thing are good but i have only one major problem with this plugin.

i use easy digital downloads plugin too. and I’m disable the default post type of this plugin because i want to use single.php for sell products.and also i use the blew code in the single.php file to show Ratings.

<?php if(function_exists('the_ratings')) { the_ratings(); } ?>

but in the HTML source of the Ratings in the post there is a problem.

see blew meta content:

<meta content="http://rokesh.ir/downloads/pinblack/" itemprop="url">

in this meta content you see the URL of the easy digital downloads plugin but i want to see the URL of the post plugin like this:

<meta content="http://rokesh.ir/wordpress-portfolio-theme-pinblack/" itemprop="url">

you can see check it online here
