Metabox v5.8.0 not working with MB Blocks

Same for me, not all mb blocks are affected only

$fields[] = [
    'title' => __('Slider', NAME_SPACE),
    'icon' => 'images-alt2',
    'category' => 'theme-blocks',
    'description' => __('Section containing an image slider', NAME_SPACE),
    'supports' => [
        'customClassName' => true,
        'anchor' => true,
    ],
    'render_callback' => 'mb_block_renderer',
    'type' => 'block',
    'context' => 'asside',
    'mode' => 'edit',
    'fields' => [
        [
            'name' => __('Heading', NAME_SPACE),
            'id' => PREFIX . 'slider_heading',
            'type' => 'text',
            'label_description' => __('Slider Heading', NAME_SPACE),
            'std' => __('Slider', NAME_SPACE),
            'required' => true,
        ],
        [
            'name' => __('Images', NAME_SPACE),
            'id' => PREFIX . 'slider_images',
            'type' => 'image_advanced',
            'label_description' => __('Slider Images', NAME_SPACE),
            'max_status' => false,
        ],
    ],
];

Same problem here. Cant add or remove field after last update. Need a fix ASAP

Hello,

Thank you for your feedback.

I've escalated this issue to the development team to fix it in the next update.

Hello,

It is fixed in the new version of Meta Box 5.8.2, please update the plugin and recheck this.
