Basic post type relationship dont work.

Hi, Im trying MB relationships plugin but after many hours I still cant use it. In WP-admin is everything OK, but when I try to query posts from template its failed. Can you take look at this bug? Its really flustrating and usseless now.

Init:

add_action( 'mb_relationships_init', function() {
    MB_Relationships_API::register( array(
        'id'   => 'articlebanner_to_articles',
        'from'   => 'm_articlebanner',
        'to'   => 'blog_article'
    ) );
} );

Query function:

function getPostBanner(){
    $connected = new WP_Query( array(
        'post_type' => 'm_articlebanner',
      'relationship' => array(
          'id' => 'articlebanner_to_articles',
          'to' => 3798,
      ),
      'nopaging' => true
    ) );

    return $connected;
}

DB records:
