Solved
All of a sudden, the subject lines on our outgoing Customer Invoice Emails are incorrect. They don't match the subject line and tags used on our Invoice Email template.
I have double-checked our Template settings and they are still saved as they always have been, i.e. "Invoice [Invoice #] from our company name". But the email subjects that are going out to customers have been everything from "New payment request from (owner's personal name - not company name as it should be)" to "(Customer name), you have a new invoice from (owner's personal name - not company name as it should be)". What is going on?! And how do we fix it, since our template settings are still set to what they have always been, and not these new subject lines?
