Image select not displaying

Hi,

here is the code it generates for one of the fields that appears blank:

<?php
add_filter( 'rwmb_meta_boxes', 'your_prefix_function_name' );

function your_prefix_function_name( $meta_boxes ) {
    $prefix = '';

$meta_boxes[] = [
    'title'  => __( 'Images', 'your-text-domain' ),
    'id'     => 'images',
    'fields' => [
        [
            'name' => __( 'Image Select', 'your-text-domain' ),
            'id'   => $prefix . 'image_select_y7qe6l7kng',
            'type' => 'image_select',
        ],
    ],
];

return $meta_boxes;
}

Does that help?

Thanks
Regine
