Redirect to Cart Not Working

Hi. I have the pro version of this plugin, with the woocommerce redirect to cart setting disabled, and the product set up so that it redirects to cart whether the customer chooses ‘yes’ or ‘no’. It works fine when they select ‘no’ but on selecting ‘yes’ they are redirected to the cross sell product page, and when selecting ‘add to cart’ nothing happens (except for ‘view cart’ appearing next to the button).

Any help would be appreciated please, as this website is meant to launch tomorrow.
