wordpress custom filter for the edit.php custom posts list

I have a custom orders posts and i wish to implement an additional filter for the list view (a select drop) in the admin menu.

I have been messing with this for hours but couldn’t find a solution. i wish to filter the posts by several meta keys and values and by post date this is the code im using for this matter

add_filter( 'parse_query', 'order_posts_filter' );

function order_posts_filter( $query ){
    global $pagenow,$wpdb;
    $type = 'post';
    if (isset($_GET['post_type'])) {
        $type = $_GET['post_type'];
    }
    if ( 'orders' == $type && is_admin() && $pagenow=='edit.php' && isset($_GET['ADMIN_FILTER_FIELD_VALUE']) && $_GET['ADMIN_FILTER_FIELD_VALUE'] != '') {
        $query->query_vars['post_date'] = $_GET['ADMIN_FILTER_FIELD_VALUE'];
    }
    if ( 'orders' == $type && is_admin() && $pagenow=='edit.php' && isset($_GET['ADMIN_FILTER_STATUS_VALUE']) && $_GET['ADMIN_FILTER_STATUS_VALUE'] != '') {
        $query->query_vars['meta_key'] = 'order_status';
        $query->query_vars['meta_value'] = $_GET['ADMIN_FILTER_STATUS_VALUE'];
    }
    return $query;
}

at the moment what im getting is that only one filter is applied.

What am i doing wrong here ? my $_GET parameters are working as expected and i am getting the relevant data from the select boxes.

thanks
