SQL syntax error near '`mbr_order` ASC, mbr_id DESC ASC'

Hello,
I'm using versions:

Meta Box 5.4.0
Meta Box AIO 1.13.9

and I'm trying to setup a reciprocal relationship between two terms of a custom taxonomy:

 MB_Relationships_API::register( [
        'id'         => 'rbi_neighboring_countries',
        'reciprocal' => true,
        'from'       => [
            'object_type' => 'term',
            'taxonomy'    => 'rbi_country',
            'meta_box'    => [
                'title' => 'Neighboring countries',
            ],
        ],
        'to'         => [
            'object_type' => 'term',
            'taxonomy'    => 'rbi_country',
        ],
    ] );

The code on the archive page:

 <?php
    $terms = get_terms(
        array(
            'taxonomy'     => 'rbi_country',
            'hide_empty'   => false,
            'relationship' => array(
                'id' => 'rbi_neighboring_countries',
                'to' => get_queried_object()->term_id,
            ),
        )
    );
    foreach ( $terms as $t ) {
        echo esc_html( $t->name );
    }
    ?>

This error is displayed in the frontend:
WordPress database error: [You have an error in your SQL syntax; check the manual that corresponds to your MariaDB server version for the right syntax to use near 'mbr_orderASC, mbr_id DESC ASC' at line 1]
SELECT t.*, tt.* , mbr.from AS mbr_from, mbr.to AS mbr_to, mbr.ID AS mbr_id, CASE WHEN mbr.to = t.term_id THEN mbr.order_from WHEN mbr.from = t.term_id THEN mbr.order_to END AS <code>mbr_order</code> FROM wp_terms AS t INNER JOIN wp_term_taxonomy AS tt ON t.term_id = tt.term_id INNER JOIN wp_mb_relationships AS mbr ON (mbr.type = 'rbi_neighboring_countries' AND ((mbr.from = t.term_id AND mbr.to IN (1)) OR (mbr.to = t.term_id AND mbr.from IN (1)))) WHERE tt.taxonomy IN ('rbi_country') <code>mbr_order</code> ASC, mbr_id DESC ASC

Seems to me like DESC ASC is the issue?
