Add vs Edit listing

Hi
I can’t quite figure where I went wrong this time.

I’m still testing my paid listings: I have added a business listing using a discount code. It publishes ok, no worries. When I now go and choose to “edit” listing, The edit screen still displays the package up the top and it still asks me to submit the listing as if it were a new listing, not editing my existing listing and then wants me to pay again.

The idea is to let someone have access to edit their listing for the term they have paid for if they need to. How do I rectify this?

Thanks
Lise
