Using WP_Query filters with get_connected()

I’m attempting to use the posts_join, posts_fields & posts_orderby filters with a query generated using get_connected()


add_filter('posts_fields' , 'cnc_posts_fields', 11, 1);
$connected = p2p_type('cast_crew_to_show')->get_connected($show_id,
array(
'posts_per_page' => -1,
'connected_meta' => array('type' => $type),
'orderby' => 'meta_value',
'order' => 'ASC',
'meta_key' => 'via_last_name'
)
);
remove_filter('posts_fields' , 'cnc_posts_fields', 11, 1);



function cnc_posts_fields($fields) {
return $fields . ', 1 AS test';
}


This will generate the following SQL query


SELECT wp_via_posts . * , 1 AS test, wp_via_p2p . *
FROM wp_via_posts
INNER JOIN wp_via_postmeta ON ( wp_via_posts.ID = wp_via_postmeta.post_id )
INNER JOIN wp_via_p2p
INNER JOIN wp_via_p2pmeta ON ( wp_via_p2p.p2p_id = wp_via_p2pmeta.p2p_id )
WHERE 1 =1
AND wp_via_posts.post_type = 'atl_cast_crew'
AND (
wp_via_posts.post_status = 'publish'
)
AND (
wp_via_postmeta.meta_key = 'via_last_name'
)
AND (
wp_via_p2p.p2p_type = 'cast_crew_to_show'
AND wp_via_posts.ID = wp_via_p2p.p2p_from
AND wp_via_p2p.p2p_to
IN (
SELECT wp_via_posts.ID, 1 AS test
FROM wp_via_posts
WHERE 1 =1
AND wp_via_posts.ID
IN ( 13467 )
AND wp_via_posts.post_type = 'atl_show'
AND (
wp_via_posts.post_status = 'publish'
)
ORDER BY wp_via_posts.post_date DESC
)
)
AND (
(
wp_via_p2pmeta.meta_key = 'type'
AND CAST( wp_via_p2pmeta.meta_value AS CHAR ) = 'Cast'
)
)
GROUP BY wp_via_posts.ID
ORDER BY wp_via_postmeta.meta_value ASC


The problem is the filter is being applied to both the main query and the subquery. I only need it on the main query.
