Your one account was opted in to using business policies.
Business policies help me keep my sanity. Manage and edit them (or disable them to go back to how you used to set up your listings) on this page.
Once you set up your shipping policies and name them so you can easily identify them, you can go to your active listings and bulk edit to assign your new policies.
After the initial mess of policies that are created when you first sign up are no longer tied to active listings, you can delete them.
It takes a little time and work to set it up, but in my opinion it's well worth it.
