There is known caching issues with W3 Super Cache plugin. We'll update this document as we have more information. In the mean time, you can try the adding the following code in your functions.php

function handl_add_wpsc_cookie_banner() {
    do_action( 'wpsc_add_cookie', 'utm_campaign' );
    do_action( 'wpsc_add_cookie', 'utm_medium' );
    do_action( 'wpsc_add_cookie', 'utm_term' );
    do_action( 'wpsc_add_cookie', 'utm_content' );
    do_action( 'wpsc_add_cookie', 'utm_source' );
}
add_action( 'init', 'handl_add_wpsc_cookie_banner' );
