Within a payment item: “no specific users = all users"

If a parent can see an old payment item that is not associated with their child this is because in ParentMail 2 if you had an item that was not linked to ANY users, nobody would be able to see it in their shop. In PMX however, if there are no users attached to a payment item, it will automatically assume that is should be available for ALL users.

Resolution: You will need to go in to each payment item that is showing incorrectly, and then link them to the correct users, or if you just want to hide this item completely – you can link it to your own staff account.
