Orderly Emails ‑ Templates App

This sounds like a great app, but for some reason it's not working for us. I've tried for 2 weeks now.

1 - The template wasn't showing our logo and requested font types, etc
then
2 - Addresses in emails (confirmations) weren't showing properly. Making our customers anxious and us looking bad.

Support - It seems that the support didn't want to acknowledge that the issue was with the app. None of these issues happened prior to installing the app.
Shopify support Tier 2, has confirmed it's the app, but Support just wont help or acknowledge it's an issue or even a POTENTIAL issue with the app.

Poor form.
