Issue with plugin rate my whatever

Hi,
for the need of a project I need to use a wp plugin like rate my whatever. This little plugin (3 files) works fine, I reached to put it on my blog template thanks to this code <?php echo apply_filters(‘the_content’,'[ratemywe]’); ?>
It works well on single pages but I have an issue on blog post listings. Percentages are displaying well but I just can vote for the first one of each page. Votes on other articles are not taken into account.
There is my test page : http://s343975158.onlinehome.fr/

Does anyone see where may come from the issue ? Maybe from the js file that set up vote process.

Regards
