Confusing PDF invoice setting

Hi.

There’s something confusing about the PDF invoice dropdown at the bottom of the Invoice Template tab.

The label for the drop down reads “Disable PDF invoice” (I’m translating from Dutch here als the client’s site is in Dutch), while the dropdown itself reads:

– Send with order confirmation
– Only on successful payment
– Only to the store admin
– Off

This is very confusing. The middle two are kind of contradictory to “Disable PDF invoice” I believe.

Could you elaborate on what each of these do exactly, and consider renaming either the label or the options for more clarity?
