Thanks for the update, WyrtWicce,
Great job for following the recommended steps provided by my colleague in this thread.
Let's perform one more troubleshooting step to get the company address working. You can delete and re-create the sales receipt after editing the address on your company settings. Doing this will make the changes take effect.
If you're still getting the same results, I highly recommend contacting our QuickBooks Online Team. They can create a ticket and send it to your Product Team for further investigation.
