Sortable Function isn’t working for Groups

Hi,

This a really great plugin that helps us a lot in our work!

But we have a problem where the Sortable Function for groups isn’t working. Even after saving the Page as noted as a solution here: https://github.com/WebDevStudios/CMB2/issues/692

We are using the following plugins:

• https://github.com/WebDevStudios/CMB2-Snippet-Library/blob/master/javascript/cmb2-js-validation-required.php
• https://github.com/WebDevStudios/cmb2-attached-posts
• https://github.com/jcchavezs/cmb2-conditionals
• https://github.com/mustardBees/cmb_field_map

Here is the code for the field:

/**
	 * Repeatable Field Groups
	 *
	 * SIDL?NKAR
	 */
	$cmb_group = new_cmb2_box( array(
		'id'           => $prefix . 'subfeatured_links_metabox',
		'title'        => __( 'Bassidor', 'cmb2' ),
		'context'      => 'after_title',
		'object_types' => array( 'page' ),
		'show_on'      => array( 'key' => 'page-template', 'value' => array( 'template-landing.php', 'template-poi.php' ) ),
	) );
	// $group_field_id is the field id string, so in this case: $prefix . 'demo'
	$group_field_id = $cmb_group->add_field( array(
		'id'          => $prefix . 'subfeatured_content',
		'type'        => 'group',
		'description' => __( 'Bassidor visas i kolumner l?ngst ned p? Landningssidan med Rubrik, Ingress och L?nk.', 'cmb2' ),
		'options'     => array(
			'group_title'   => __( 'Bassida {#}', 'cmb2' ), // {#} gets replaced by row number
			'add_button'    => __( 'L?gg till Bassida', 'cmb2' ),
			'remove_button' => __( 'Ta bort Bassida', 'cmb2' ),
			'sortable'      => true, // beta
			'closed'     => false, // true to have the groups closed by default
		),
	) );
	/**
	 * Group fields works the same, except ids only need
	 * to be unique to the group. Prefix is not needed.
	 *
	 * The parent field's id needs to be passed as the first argument.
	 */

	$cmb_group->add_group_field( $group_field_id, array(
		'name'    => __( 'Bassida', 'cmb2' ),
		'desc'    => __( 'V?lj bassida att visa. Rubrik, Ingress och L?nk h?mtas automatiskt.', 'cmb2' ),
		'id'      => 'attached_cmb2_attached_posts',
		'type'    => 'custom_attached_posts',
		'options' => array(
			'show_thumbnails' => true, // Show thumbnails on the left
			'filter_boxes'    => false, // Show a text box for filtering the results
			'query_args'      => array( 'post_type'=>array( 'page'), 'posts_per_page' => -1, 'post_parent' => $_GET['post'] ), // override the get_posts args
			'max_attached'    => true
		),
	) );

   $cmb_group->add_group_field( $group_field_id, array(
		'name' => 'Anpassa',
		'id'   => 'custom_content_checkbox',
		'type' => 'checkbox',
		'description' => 'Kryssa i denna ruta f?r att anpassa: Rubrik, Ingress, L?nk och/eller L?nktext. OBS! Kryssa ?ven i denna rutan om du vill l?nka till n?got som inte ?r en undersida.'
	) );

	$cmb_group->add_group_field( $group_field_id, array(
		'name'       => __( 'Anpassad rubrik', 'cmb2' ),
		'id'         => 'heading',
		'type'       => 'text',
		'attributes' => array(
			'data-conditional-id'    => wp_json_encode( array( $group_field_id, 'custom_content_checkbox' ) ),
			'data-conditional-value' => 'on',
		),
	) );
	$cmb_group->add_group_field( $group_field_id, array(
		'name'        => __( 'Anpassad ingress', 'cmb2' ),
		//'description' => __( '', 'cmb2' ),
		'id'          => 'content',
		'type'        => 'textarea_small',
		'attributes' => array(
			'data-conditional-id'    => wp_json_encode( array( $group_field_id, 'custom_content_checkbox' ) ),
			'data-conditional-value' => 'on',
		),
	) );

	$cmb_group->add_group_field( $group_field_id, array(
		'name'       => __( 'Anpassad l?nk', 'cmb2' ),
		'id'         => 'link_picked',
		'type'       => 'link_picker',
		'attributes' => array(
