Reply To: Invoice not attached to email after payment

I don’t have any other select options other than “Standard” for the first 2 settings (Main invoice template, Guest Invoice template).

Lower down under “Email Attachment generated by guest template” checkboxes, the select boxes have 2 options “Standard” & “Guest Template”.

And lower down the page in the template editor I only have one template “Standard” – hence why ive set all my options to “standard”.

Have I missed something?
