Calculation in cart without result

Good morning, I installed the plugin in the free version for testing, I loved the result of the hackout, however it delays the shipping calculation in the cart a lot or presents no available options.
Normally it presents no available options, then you go to checkout and it calculates the shipping and when you return to the cart it is there.
Having a good checkout is great, but not delivering shipping to the customer before checkout is complicated. Is there a wrong configuration, can you help me?
