Hi @Wajdy - you are correct, it works the same for me.

I can copy the invoice and it will show correct. It will not show correct on the original. My problem is that now the copied invoice is not linked to the estimate. A work around is fine but we can all agree that this problem needs to be fixed asap. I don't want to loose that link, so currently I am typing up Word Invoices manually and sending them as pdf attachments as I never used the "send invoice" feature anyway. It's just a lot of extra work and it is more sensitive to mistakes. 

Quickbooks team, I have escalated this issue 2 times in the past over the phone, and never received follow-ups. Please let us know that this is a priority and getting worked on 24/7!
