Default preferred billing address is not saving

I can't save my new address as the default billing address in account's settings (https://account.microsoft.com/billing/addresses). Everytime I select needed address - the page says that it was successfully saved as preferred billing address, but in fact there's still a "No default address" in that column. Preferred delivery address saves correctly though. I can't purchase anything on Xbox without default billing address being set.

I've already tried adding new entries, deleting everything and then add again, but it still says "No default address".
