Invoice does not select shipping method

-- url of the page with the problem -- : umbandaexplica.com.br/loja/
-- HikaShop version -- : 3.4

In my invoice in the "Additional Information" field, where you have the sub-total and total (shipping method and etc.), the option of sending the customer does not automatically appear.

I need to select it automatically so it can be printed on the invoice. Only the payment option is automatic.

see the image

Shows only the backend code of the "PAC - PAC"

Hi,

Did you add the "shipping" view in the "checkout workflow" setting of the HikaShop configuration ?
Could you provide a screenshot of the settings under the "checkout" tab of the HikaShop configuration ?
And you could also provide a screenshot of the settings of your shipping methods in System>Shipping methods ?
