Metabox group and admin-ajax.php

I have a page with a fair amount of content using the metabox group plugin (see code below). it seems to hammer admin-ajax with calls on page load. I have all the latest versions, and no other plugins installed. Wondering if you had a work around for this or any ideas what is happening?

$meta_boxes[] = array(
	'id'		=> 'page_title',
	'title'		=> 'Project Page',
	'pages'		=> array( 'page'),
	'show'   => array(
		'relation'    => 'OR',
		'template'    => array( 'tmpl.projects.php'),
	
	),
	'fields'	=> array(
			
			array(
				'id'     => 'project_item',
				'type'   => 'group',
				'clone'  => true,
				'max_clone' => 99,
				'sort_clone' => true,
				'collapsible' => true,
				'group_title' => 'Project',
				'fields' => array(
					array(
						'name'    => __( 'Link', 'rwmb' ),
						'id'      => "{$prefix}project_link",
						'type'    => 'post',
						'clone'    => false,			
				     	'force_delete' => true,
				        'std'   => '',
						'post_type' => 'post',
						'field_type' => 'select_advanced',
						'query_args' => array(
							'post_status' => 'publish',
							'posts_per_page' => '-1',
						)
					),

					array(
						'name' => __( 'Image', 'rwmb' ),
						'id'               => "{$prefix}project_image_teaser_full",
						'type'             => 'image_advanced',
						'max_file_uploads' => 1,
						'clone'		=> false,

					),
					array(
						'name' => __( 'Portrait Image', 'rwmb' ),
						'id'               => "{$prefix}project_image_teaser_portrait",
						'type'             => 'image_advanced',
						'max_file_uploads' => 1,
						'clone'		=> false,

					),
					
					array(
						'name' => __( 'Heading', 'rwmb' ),
						'desc' => __( '', 'rwmb' ),
						'id'   => "{$prefix}project_name",
						'type' => 'textarea',
						'cols' => 10,
						'rows' => 4,
					),
					
					

					
				),
			),

	)
);
