WYSIWYG editor not loading the editor but the raw HTML code

[q2amarket]

I am trying to add this into my plugin for CPT. Here is my code. I hope it is correct. However, the editor is not loading but outputting raw HTML code as below.

Method

public function add_card_meta_boxes( array $meta_boxes ) {

    $meta_boxes[] = [
        'title'    => 'Add Card Items',
        'pages'    => 'card',
        'context'  => 'normal',
        'priority' => 'high',
        'fields'   => [
            [
                'id'                  => 'item_group',
                'name'                => 'Item Group',
                'type'                => 'group',
                'repeatable'          => TRUE,
                'string-repeat-field' => 'Add Item',
                'tring-delete-field'  => 'Remove Item',
                'fields'              => [
                    [
                        'id'   => 'item_title',
                        'name' => 'item title',
                        'type' => 'text',
                    ],
                    [
                        'id'      => 'example-field-wysiwyg',
                        'name'    => 'A WYSIWYG editor field',
                        'type'    => 'wysiwyg',
                        'options' => [
                            'textarea_rows' => 5
                        ]
                    ]
                ]
            ]
        ],
        'desc'     => 'Add card items for the card.',
    ];

    return $meta_boxes;

}

Output for WYSIWYG

<div id="wp-item_group-cmb-group-0-example-field-wysiwyg-cmb-field-0-wrap" class="wp-core-ui wp-editor-wrap tmce-active"><link rel="stylesheet" id="editor-buttons-css" href="http://apollocorner.co/wp-includes/css/editor.min.css?ver=4.7.5" type="text/css" media="all" /><div id="wp-item_group-cmb-group-0-example-field-wysiwyg-cmb-field-0-editor-tools" class="wp-editor-tools hide-if-no-js"><div id="wp-item_group-cmb-group-0-example-field-wysiwyg-cmb-field-0-media-buttons" class="wp-media-buttons"><button type="button" id="insert-media-button" class="button insert-media add_media" data-editor="item_group-cmb-group-0-example-field-wysiwyg-cmb-field-0"><span class="wp-media-buttons-icon"></span> Add Media</button></div><div class="wp-editor-tabs"><button type="button" id="item_group-cmb-group-0-example-field-wysiwyg-cmb-field-0-tmce" class="wp-switch-editor switch-tmce" data-wp-editor-id="item_group-cmb-group-0-example-field-wysiwyg-cmb-field-0">Visual</button><button type="button" id="item_group-cmb-group-0-example-field-wysiwyg-cmb-field-0-html" class="wp-switch-editor switch-html" data-wp-editor-id="item_group-cmb-group-0-example-field-wysiwyg-cmb-field-0">Text</button></div></div><div id="wp-item_group-cmb-group-0-example-field-wysiwyg-cmb-field-0-editor-container" class="wp-editor-container"><div id="qt_item_group-cmb-group-0-example-field-wysiwyg-cmb-field-0_toolbar" class="quicktags-toolbar"></div><textarea class="wp-editor-area" rows="5" autocomplete="off" cols="40" name="item_group[cmb-group-0][example-field-wysiwyg][cmb-field-0]" id="item_group-cmb-group-0-example-field-wysiwyg-cmb-field-0"></textarea></div></div>

@q2amarket Can you tell me which branch of the plugin you're using?

[q2amarket]

Your question is right. I was using older version. I have updated it to CM2 and all is well. Thanks for the great lib.
