multiple loops and qtranslate

I’m using a customized theme and I’m translating my content with qtraslate,

qtranslate works fine on the first loop but the problem is that when I use a second loop in my template, it shows the content twice, one in the default language an the other in the language it’s supposed to,

here’s what I use for the second loop:

<?php $list_of_services = new WP_Query( 'cat=4');
        if ($list_of_services->have_posts()) : while($list_of_services->have_posts()) : $list_of_services->the_post();?>
            <?php get_template_part( 'content', get_post_format() ); ?>
        <?php endwhile; endif; ?>
        <?php wp_reset_postdata();?>

Since I’ve created this theme from ground up I maybe missing something , any ideas are welcome.
