Choice fields filter not working on clonable field

Hi Ryan,

I’ve just done a quick test and it works for me. Here is the code I’m using to register a meta box and filter the label:

add_filter( 'rwmb_meta_boxes', function( $meta_boxes ) {
    $meta_boxes[] = [
        'title' => 'Cloneable Post Field',
        'fields' => [
            [
                'id' => 'p',
                'title' => 'Post',
                'type' => 'Post',
                'clone' => true,
            ],
        ],
    ];
    return $meta_boxes;
} );

add_filter( 'rwmb_p_choice_label', function ( $label, $field, $post ) {
    return "$post->post_type: $post->post_title";
}, 10, 3 );

And here is the screenshot:

Oh, I see the problem. After saving, only the 1st input has the filter working. I’ll fix it now.
