Programming in Woocommerce

I have a site for manufactured products (which are charged shipping) and dropshipping products integrated with AliExpress (with free shipping), which when mixing the two in the cart gives an error and the information appears that there is no shipping to the selected address. It only works to mix the two in outsourced checkouts like Yampi and Cartx, but not woocommerce. I would like a css code to resolve this issue with someone who understands about.
