Problem solved on the wrong company showing in the bank statement.

As it says when installing the mod,
Enter the (Store) Location ID from your account settings. You can have multiple locations configured in your account; this setting lets you specify which location your sales should be attributed to. If you want to enable Apple Pay support, this location must already be verified for Apple Pay in your Square account.
What they don't tell you is that you have to create the locations in a different area from the Application itself.

Your extra locations can be created at https://squareup.com/dashboard/locations
