I believe the default invoice template contains these tokens. They do not work and display exactly what is being described.
The default templates should be fixed to display a proper invoice rather than expecting everyone to customize it just to make it work.
Ideally, an address and city line should be added to Manage Cart Settings. Then, the default invoice template should be modified to use these tokens to populate the invoice header from the cart settings.

IMO, the default invoice template should display a printable invoice, including the bill to and ship to information and it should work out of the box.
