email is always required

Hey Peter,

I switched to the 2023 theme, deactivated all plugins except

MB Custom Post Types & Custom Taxonomies
MB Settings Page
MB User Meta
Meta Box
Meta Box Builder
Meta Box Group

The Meta Box Builder PHP Export is:

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

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

    $meta_boxes[] = [
        'title'  => __( 'Paten-Profil', 'your-text-domain' ),
        'id'     => 'user-profile',
        'type'   => 'user',
        'fields' => [
            [
                'name' => __( 'Profil-Bild', 'your-text-domain' ),
                'id'   => $prefix . 'profile_image',
                'type' => 'single_image',
            ],
            [
                'name'       => __( 'Fragen und Antworten', 'your-text-domain' ),
                'id'         => $prefix . 'qa',
                'type'       => 'group',
                'clone'      => true,
                'sort_clone' => true,
                'fields'     => [
                    [
                        'name'       => __( 'Frage', 'your-text-domain' ),
                        'id'         => $prefix . 'question',
                        'type'       => 'taxonomy_advanced',
                        'field_type' => 'select_advanced',
                    ],
                    [
                        'name' => __( 'Antwort', 'your-text-domain' ),
                        'id'   => $prefix . 'answer',
                        'type' => 'wysiwyg',
                    ],
                ],
            ],
            [
                'name'              => __( 'E-Mail', 'your-text-domain' ),
                'id'                => $prefix . 'email',
                'type'              => 'email',
                'label_description' => __( 'Abweichende E-Mail-Adresse', 'your-text-domain' ),
                'desc'              => __( 'Wenn keine E-Mail-Adresse eingetragen wird, wird die E-Mail-Adresse dieses Kontos verwendet.', 'your-text-domain' ),
            ],
            [
                'name' => __( 'Crew United ID', 'your-text-domain' ),
                'id'   => $prefix . 'cu_id',
                'type' => 'text',
            ],
            [
                'name'       => __( 'Patenschaft', 'your-text-domain' ),
                'id'         => $prefix . 'mentoring',
                'type'       => 'taxonomy',
                'field_type' => 'select_advanced',
                'multiple'   => true,
            ],
        ],
    ];

    return $meta_boxes;
}

the problem still persists

Hey Peter,

I assume you have not tried to update the profile. However, I solved it. It should also happen on your site. This only happens if the field ID is 'email'. I guess it conflicts with the native email field.
