Switch On default renders off on user profile

Hi,

I have a custom group using the code below.
as can be seen, the switch 'std' value is true, which should render the switch as on, by default but renders off.

Case 2:
A few days ago I had another situation where 'std' was on, the group in which the switch was in was cloneable. The first switch was on, but when I cloned the parent group, the other switch buttons were off. I could not reproduce this case as I cannot remember the exact settings.

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

    $meta_boxes[] = [
        'title'  => __( 'User Stores', 'your-text-domain' ),
        'id'     => 'custom-fields-group-user-stores',
        'type'   => 'user',
        'fields' => [
            [
                'name'              => __( 'User Stores', 'your-text-domain' ),
                'id'                => $prefix . 'user_stores',
                'type'              => 'group',
                'clone'             => true,
                'clone_as_multiple' => true,
                'add_button'        => __( 'Add Store', 'your-text-domain' ),
                'fields'            => [
                    [
                        'name'       => __( 'Store', 'your-text-domain' ),
                        'id'         => $prefix . 'store',
                        'type'       => 'post',
                        'post_type'  => ['store'],
                        'field_type' => 'select_advanced',
                        'required'   => true,
                    ],
                    [
                        'name' => __( 'Active', 'your-text-domain' ),
                        'id'   => $prefix . 'active',
                        'type' => 'switch',
                        'std'  => true,
                    ],
                ],
            ],
        ],
    ];

    return $meta_boxes;
}
