By default, your address for each location will be printed based on the information you have entered in the location information under settings. If you add an address to the "header" under receipts then your receipt will have two addresses.

To correct this go to Settings -> Receipts -> Templates and remove the address from the "header" section. Then go to Settings -> Locations and verify that each location has the correct address listed for us to display at the top of your receipts.

Now your receipts will display the correct address for the corresponding location!
