Thank you for your reply. Yes, I took the steps suggested in your previous post but they did not resolve the problem.

I have used the online and desktop QB versions with the same results. I am on a MacBook Pro running OS 10.14.2. 

My immediate work around is downloading the estimate / invoice and editing the PDF in Acrobat Pro. This is not ideal but is getting me through until the issues is corrected with an update or verified steps to resolve.

Thank you!
