You have a meta generator line for WordPress and one for WooCommerce.

you should be able to remove the WooCommerce one by adding the following to your theme' functions.php

function remove_woo_commerce_generator_tag()
{
    remove_action('wp_head',array($GLOBALS['woocommerce'], 'generator'));
}
add_action('get_header','remove_woo_commerce_generator_tag');
