After specifying a zone, the delivery method stops working

-- Joomla version -- : 5.1.2
-- PHP version -- : 8.1


Hello. I apologise if there is already an explanation for all this.

I set up a delivery method, everything works until I try to set a zone. After that the method is not available for all countries but for the one in which it should also work.

Thank you very much for your help!

Thank you very much for your reply. It is possible to make it so that there was a button to confirm the address and only then the delivery options appeared.

Now I have after filling out one of the delivery methods is immediately visible and address confirmation occurs only after clicking the finish button, which seems to me not quite intuitive.

thank you very much again!
