Double entries with multiple connections

First of all: thanks for this great plugin!

I’m having an issue using the method as described on the Wiki page (https://github.com/scribu/wp-posts-to-posts/wiki/Actions-and-filters).

I have a post-type ‘adviseur’, that is connected to pages. I use a custom template for the Posts2Posts widget (p2p-ul-adviseur_to_page.php). In the widget I want to show the connected adviseur, with some meta data, so I’m using this query & code:

// Get connected adviseurs
$connected = new WP_Query( array(
        'connected_type' => 'adviseur_to_page',
        'connected_items' => get_queried_object(),
        'nopaging' => true,
    ) );

 // Display connected adviseurs
    ?>
    <div class="adviseurs-block">
    <?php

    if( $connected->have_posts() ) { ?>
    <h4>Uw adviseur(s):</h4>
    <?php
    while ( $connected->have_posts() ) : $connected->the_post(); ?>
        <div class="adviseur">
        <h5><?php the_title(); ?></h5>
            <?php lwd_do_adviseur_archive_content() ?>
        </div><!-- end .adviseur -->
    <?php
    endwhile;
    }

    wp_reset_postdata(); // set $post back to original post
    ?>
</div><!-- end .adviseurs-block -->

The function lwd_do_adviseur_archive_content shows some metafield values from the adviseur post type.

All works well, except when I connect more then one adviseur to a page: then it shows all connected adviseurs twice. If I use the query in a page template it doesn’t show this behavior…What am I doing wrong?

Thanks in advance!
