Not show Taxonomy field values in MB Blocks

Hi,
I have a problem using a taxonomy field in MB Blocks. I create a block containing a field with ‘type’ => ‘taxonomy’. I can set a value for this field in the block editor, but when I leave the post and then return I do not see the previously set value even when the value in the database is well stored. Can you help me?
This is the custom taxonomy:

add_action( 'init', 'your_prefix_register_taxonomy' );
function your_prefix_register_taxonomy() {
    $labels = [
        'name'                       => esc_html__( 'Test Types', 'your-textdomain' ),
        'singular_name'              => esc_html__( 'Test Type', 'your-textdomain' ),
        'menu_name'                  => esc_html__( 'Test Types', 'your-textdomain' ),
        'search_items'               => esc_html__( 'Search Test Types', 'your-textdomain' ),
        'popular_items'              => esc_html__( 'Popular Test Types', 'your-textdomain' ),
        'all_items'                  => esc_html__( 'All Test Types', 'your-textdomain' ),
        'parent_item'                => esc_html__( 'Parent Test Type', 'your-textdomain' ),
        'parent_item_colon'          => esc_html__( 'Parent Test Type', 'your-textdomain' ),
        'edit_item'                  => esc_html__( 'Edit Test Type', 'your-textdomain' ),
        'view_item'                  => esc_html__( 'View Test Type', 'your-textdomain' ),
        'update_item'                => esc_html__( 'Update Test Type', 'your-textdomain' ),
        'add_new_item'               => esc_html__( 'Add new test type', 'your-textdomain' ),
        'new_item_name'              => esc_html__( 'New test type name', 'your-textdomain' ),
        'separate_items_with_commas' => esc_html__( 'Separate test types with commas', 'your-textdomain' ),
        'add_or_remove_items'        => esc_html__( 'Add or remove test types', 'your-textdomain' ),
        'choose_from_most_used'      => esc_html__( 'Choose most used test types', 'your-textdomain' ),
        'not_found'                  => esc_html__( 'No test types found', 'your-textdomain' ),
        'no_terms'                   => esc_html__( 'No test types found', 'your-textdomain' ),
        'items_list_navigation'      => esc_html__( 'Test types list pagination', 'your-textdomain' ),
        'items_list'                 => esc_html__( 'Test Types list', 'your-textdomain' ),
        'most_used'                  => esc_html__( 'Most Used', 'your-textdomain' ),
        'back_to_items'              => esc_html__( 'Back to test types', 'your-textdomain' ),
        'text_domain'                => esc_html__( 'your-textdomain', 'your-textdomain' ),
    ];
    $args = [
        'label'              => esc_html__( 'Test Types', 'your-textdomain' ),
        'labels'             => $labels,
        'description'        => '',
        'public'             => true,
        'publicly_queryable' => true,
        'hierarchical'       => false,
        'show_ui'            => true,
        'show_in_menu'       => true,
        'show_in_nav_menus'  => true,
        'meta_box_cb'        => true,
        'show_in_rest'       => true,
        'show_tagcloud'      => true,
        'show_in_quick_edit' => true,
        'show_admin_column'  => false,
        'query_var'          => true,
        'sort'               => false,
        'rest_base'          => '',
        'rewrite'            => [
            'with_front'   => false,
            'hierarchical' => false,
        ],
    ];
    register_taxonomy( 'test-type', ['test-pt'], $args );
}

This is the block:

add_filter( 'rwmb_meta_boxes', 'your_prefix_register_meta_boxes' );

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

    $meta_boxes[] = [
        'title'    => esc_html__( 'Test BLCK', 'text-domain' ),
        'id'       => 'test-blck',
        'fields'   => [
            [
                'id'   => $prefix . 'text_hdsmywqrchf',
                'type' => 'text',
                'name' => esc_html__( 'Text Field Test BLCK', 'text-domain' ),
            ],
            [
                'id'         => $prefix . 'taxonomy_rjokxm5oyo9',
                'type'       => 'taxonomy',
                'name'       => esc_html__( 'Taxonomy Field', 'text-domain' ),
                'taxonomy'   => 'test-type',
                'field_type' => 'select',
            ],
        ],
        'category' => 'layout',
        'icon'     => 'admin-appearance',
        'type'     => 'block',
        'mode'     => 'edit',
    ];

    return $meta_boxes;
}

And this is the problem:
