posts_clauses drop ACF get_field function

Hello
I try to use function for order by stock status in my store catalog but this code drop ACF get_field() function
when function on, get_field return only ID of post (https://skr.sh/sGyfgZ3GwaP)
and when function off, all right, get_field return array (https://skr.sh/sGyHPC9UUOw)
please help me to find a reason

add_filter( 'posts_clauses', 'order_by_stock_status', 2000 );
function order_by_stock_status( $posts_clauses ) {
global $wpdb;

if ( is_woocommerce() && ( is_shop() || is_product_category() || is_product_tag() || is_product_taxonomy() ) ) {
    $posts_clauses['join'] .= " INNER JOIN $wpdb->postmeta istockstatus ON ( $wpdb->posts.ID = istockstatus.post_id ) ";
    $posts_clauses['orderby'] = " istockstatus.meta_value ASC, " . $posts_clauses['orderby'];
    $posts_clauses['where'] = " AND istockstatus.meta_key = '_stock_status' AND istockstatus.meta_value <> '' " . $posts_clauses['where'];
}
return $posts_clauses;
}
