12 Columns not working

I noticed also now, if i generate the PHP for it, it looks like this:

11 COLUMNS:

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

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

    $meta_boxes[] = [
        'title'          => __( 'Driftdokument - Systeminfo', 'your-text-domain' ),
        'id'             => 'driftdokument-systeminfo',
        'post_types'     => ['drift-dokument'],
        'closed'         => true,
        'default_hidden' => false,
        'autosave'       => true,
        'revision'       => true,
        'storage_type'   => 'custom_table',
        'table'          => 'wpinsidan_drift_dokument',
        'fields'         => [
            [
                'name'              => __( 'Wysiwyg', 'your-text-domain' ),
                'id'                => $prefix . 'wysiwyg_u9wdm8qq34e',
                'type'              => 'wysiwyg',
                'raw'               => false,
                'required'          => false,
                'clone'             => false,
                'clone_empty_start' => false,
                'columns'           => 11,
                'hide_from_rest'    => false,
                'hide_from_front'   => false,
                'limit_type'        => 'character',
            ],
        ],
    ];

    return $meta_boxes;
}

12 COLUMNS:

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

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

    $meta_boxes[] = [
        'title'          => __( 'Driftdokument - Systeminfo', 'your-text-domain' ),
        'id'             => 'driftdokument-systeminfo',
        'post_types'     => ['drift-dokument'],
        'closed'         => true,
        'default_hidden' => false,
        'autosave'       => true,
        'revision'       => true,
        'storage_type'   => 'custom_table',
        'table'          => 'wpinsidan_drift_dokument',
        'fields'         => [
            [
                'name'              => __( 'Wysiwyg', 'your-text-domain' ),
                'id'                => $prefix . 'wysiwyg_u9wdm8qq34e',
                'type'              => 'wysiwyg',
                'raw'               => false,
                'required'          => false,
                'clone'             => false,
                'clone_empty_start' => false,
                'hide_from_rest'    => false,
                'hide_from_front'   => false,
                'limit_type'        => 'character',
            ],
        ],
    ];

    return $meta_boxes;
}

So on 12 columns, it doesn't generate columns => 12.

Hello,

Well, even if we select no columns data, it looks like in the images. It doesn't go 100%.
It just looks completely broken.

How can we solve this?

Here is more data for debug.

I have 2 custom fields created, one works, one don't.

Both have 12 columns selected (i tried empty as well) and the source code looks like this: https://imgur.com/a/1ZekzUD

They are different.

Let me know what you think.

Hello!

I use only the builder for all fields.
Can i do some workaround for it to work until there is a fix?

Thanks
