Radio inputs revert to default after save

Hello,
After a recent update the metabox that I set up to control visibility on some ecommerce pages has quit updating on existing posts.

I use to be able to click through the radio inputs and have the data stick, now if I try to change radio input it will revert back to the default when the page is saved/ updated.

Currently I am having the client delete the metadata on the page and re-click the desired input.

I set it up a while back using the code from the demo, what am I missing or need to change to fix this?

Thanks in Advance

add_filter( 'rwmb_meta_boxes', 'xxx_register_meta_boxes' );
    function xxx_register_meta_boxes( $meta_boxes ) {
    		$prefix = 'xxx_';
        $meta_boxes[] = array(
        		'id' => 'standard',
            'title'      => __( 'Pricing Visability', 'rwmb'  ),
            'pages' => array( 'post', 'page','wpsc-product' ),
            'context' => 'side',
            'priority' => 'high',
            'fields'     => array(
                array(
					'name'    => __( '', 'rwmb' ),
					'id'      => "{$prefix}radio",
					'type'    => 'radio',
					'options' => array(
						'1' => __( 'Show Price', 'rwmb' ),
						'2' => __( 'Out of Stock', 'rwmb'),
						'3' => __( 'Call for Info', 'rwmb' ),
					),
				),
            ),
        );
        return $meta_boxes;
