Conditional Shipping Methods

Hi, I have installed the conditional shipping for woocommerce, we have a few small products which we would like to use a small courier for when customers purchase these items. I have set up the conditions and rule set but when I test and add the products to the cart the option for courier does not show and only the main shipping shows. I need some help to adjust this. And if clients orders from the larger products and adds a smaller product to their cart, then only the main shipping should show. Any assistance would be great.
