Ahhh...you are using a different template...that is customer/main/cart_details.tpl. Replace this:

{if $products[prod_num].productcode}{$products[prod_num].productcode}{else}#{$products[prod_num].productid}{/if}. {$products[prod_num].product|truncate:"30":"...":true}

with this:

{$products[prod_num].product}
