Weird string in address on invoice

Heather Zacny
8005 Hickory St
75034 Frisco state_Texas_4307
United States of America
Telephone: 9728243169


How do I change the above?

It should read:

8005 Hickory St
Frisco, TX 75034

I don't need the country shown.

If you see the namekey of the state instead of the state name in an address, it's because you deleted/unpublished the state in the System->Zones menu.

If you want to change the address display, you need to edit the two files address_template via the menu Display->Views.
