[Plugin: Posts 2 Posts] WP_Query() x get_posts()

These values are in database table:

id,from,to
2,2478,3910
3,4075,3910

I tried to connect posts to pages, so there are two posts (2478 and 4075) connected to page 3910.

Then I wanted to list connected posts to my page:

$sc_query = new WP_Query( array(
  'suppress_filters' => false,
  'post_type' => 'post',
  'connected_to' => $post->ID) );

if($sc_query->have_posts()) :

echo '<ul>';

while($sc_query->have_posts()):$sc_query->the_post(); ?>
<li><a href="<?php the_permalink(); ?>"><?php the_title(); ?></a></li>

<?php
endwhile;
echo '</ul>';
endif;
wp_reset_query();

$post->ID is correct 3910, but there are both connected posts with many others? I do not understand why, because in p2p table are only these 2 rows?

And when I use get_posts(), everything works well:

$connected = get_posts( array(
  'suppress_filters' => false,
  'post_type' => 'post',
  'connected_to' => $post->ID,
) );

echo '<ul>';

foreach( $connected as $post ) : setup_postdata($post); ?>
<li><a href="<?php the_permalink(); ?>"><?php the_title(); ?></a></li>
<?php endforeach;

echo '</ul>';

I am out of ideas… Same query, different results?
