Metabox title/description don't show on taxonomy term pages

[MickeyKay]

Neither the title nor description fields appear to be outputting when using CMB2 metaboxes with WordPress 4.4's new term meta functionality.

Update
This issue relates specifically to the cmb2-rest-api branch.

I suggest using the 'title' field type to output titles (and the description attribute on that title field to output a description). It works the same way for user meta as well.

Sorry, should've been clearer here. I was racing along to get things done and didn't leave you much to work with. Keep in mind this is referring to the cmb2-rest-api branch specifically. What I'm referring to are the title and description args passed to the new_cmb2_box() call. Here's my code:

public function register_category_related_content_metabox() {

    // Start with an underscore to hide fields from custom fields list
    $prefix = "_{$this->plugin_slug}_";

    $metabox = new_cmb2_box( array(
        'id'           => $prefix . 'related-content-group',
        'title'        => __( 'TITLE', 'my-slug' ),
        'description'        => __( 'DESCRIPTION', 'my-slug' ),
        'object_types' => array( 'term' ),
        'taxonomies'   => array( 'category', 'post_tag' ),
    ) );

    $metabox->add_field( array(
        'name'             => __( 'Related Content Group', 'my-slug' ),
        'id'               => $prefix . 'related-content-group',
        'type'             => 'select_related_content_group',
        'options_cb'       => array( $this, 'get_related_content_type_groups' ),
        'show_option_none' => __( '- None -', 'my-slug' ),
    ) );

}

And here's what outputs on taxonomy term pages:

As you can see, the metabox title and description are not outputting at all.

Yes, I understood. As i mentioned, that is how it has always been when using CMB2 anywhere but in an actual metabox. User/Term meta fields do not live in a metabox, but are standalone fields. If you want to create that separation, use the 'title' field type.

Got it. Thanks.
