How to get delivery groups correctly?

[Mathgobbo]

Hey guys! How can I make the delivery address to load correctly after setting the cart address?
After changing the delivery address and going to the checkout page, the shipping options load correctly, and if I go back to the cart page it loads the delivery groups correctly too. But if I try to update the delivery address again inside the cart page, it cleans up the delivery groups options.
This is the action that I'm calling to set the delivery address:

    case CartForm.ACTIONS.DeliveryAddressesAdd:
      if (!cep) break;
      // API to get full address from ZipCode
      const res = await fetch(`https://viacep.com.br/ws/${cep}/json/`);
      const json = (await res.json()) as ViaCepResponse;

      // Adding the address
      result = await cart.addDeliveryAddresses([
        {
          selected: true,
          address: {
            deliveryAddress: {
              city: json.localidade,
              countryCode: 'BR',
              provinceCode: json.estado,
              zip: cep as string,
              address1: json.logradouro,
              address2: json.complemento, 
            },
          },
        },
      ]);
      break;

It doesnt work logged in, logged out either.
If someone provide an example, would be great.
Thank you!
