当用户的角色不同于时，我在查询WP\\U查询对象时遇到问题administrator

我的WP\\U查询如下：

function remove_new_c_post($author_id,$value_id) {

        $query = new WP_Query( array(
            \'post_type\' => \'custom_post_type\',
            \'author\' => $author_id,
            \'meta_query\' => array(
            \'relation\' => \'AND\',
                array(
                    \'key\'     => \'value_id\',
                    \'value\'   => $value_id,
                    \'compare\' => \'LIKE\',
                ),
            ),
            \'order\' => \'ASC\'

            ));

        if ( $query->have_posts() ) : while ( $query->have_posts() ) : $query->the_post();
            wp_delete_post( get_the_ID() );
        endwhile;
        wp_reset_postdata();
        endif;

}

由于某种原因，当查询由管理员以外的用户运行时，结果如下：

WP_Query Object
(
    [query] => Array
        (
            [post_type] => custom_post_type
            [author] => 70
            [meta_query] => Array
                (
                    [relation] => AND
                    [0] => Array
                        (
                            [key] => value_id
                            [value] => 86
                            [compare] => LIKE
                        )

                )

            [order] => ASC
        )

    [query_vars] => Array
        (
            [post_type] => custom_post_type
            [author] => 86 //<--- THIS SHOULD BE 70
            [meta_query] => Array
                (
                    [relation] => AND
                    [0] => Array
                        (
                            [key] => value_id
                            [value] => 86
                            [compare] => LIKE
                        )

                ) 
            [order] => ASC
...

请注意中的作者query_vars 应该是70的时候是86。为什么要修改？

EDIT:

我刚刚尝试设置query\\u var$query->set( \'author\', $author_id ); 它保持了作者id的完整性；然而，mysql不断被修改：

  [request] => SELECT SQL_CALC_FOUND_ROWS  dlwp_posts.ID
               FROM dlwp_posts
               INNER JOIN dlwp_postmeta ON ( dlwp_posts.ID = dlwp_postmeta.post_id )   
               WHERE 1=1  AND dlwp_posts.post_author IN (86)
                 AND dlwp_posts.post_type = \'custom_post_type\'
                 AND (dlwp_posts.post_status = \'publish\'
                   OR dlwp_posts.post_status = \'future\'
                   OR dlwp_posts.post_status = \'draft\'
                   OR dlwp_posts.post_status = \'pending\'
                   OR dlwp_posts.post_status = \'private\')
                 AND (( dlwp_postmeta.meta_key = \'value_id\'
                   AND CAST(dlwp_postmeta.meta_value AS CHAR) LIKE \'%86%\' )

function problematic_parent_action( &$query ) {
  if ($query->is_author) {
    $query->set( \'post_type\', array( \'problematic_parent_post_type\' ) );
  }
}
add_action( \'pre_get_posts\', \'problematic_parent_action\' );

function remove_problematic_parent_action() {
  remove_action( \'pre_get_posts\', \'problematic_parent_action\' );
}
add_action( \'init\', \'remove_problematic_parent_action\');
