I cannot see those “status” at Invoices > Invoices
Maybe you mean in your PayPal account?
I think you had a package that was monthly for six months. So 2/6 would mean it would be the second payment of 6.
So two payments are “completed” and 4 to go.
I am guessing paid means that the invoices are paid already, and renewal means they are future payments that will be taken out of your customers’ accounts.
Please be aware that changing a package has no effect on existing packages.
If a customer has agreed to 6 monthly payments, then changing a package to never stop taking monthly payments cannot change a contract made between your customer and PayPal.
Changes to packages will only apply to new listings made from the frontend, after the changes are made.
Thanks
