Email Header & Footer Not Showing Up In Invoices

[Xarcell]

I have created a custom header & footer for the emails in general settings. I have not touched the custom emails yet. If I go to "clients > client name > send message", the email shows the header & footer. However, with invoices, the header & footer do not appear. the code is entirely different. What am I doing wrong?

Invoices don't use those header/footers.

If you want to customize the invoice , see PDF Invoice Customization

Only the emails themselves use those headers/footers.
