I have recently added the subscription app Subbox: subscriptions. Love all it does however when one goes to check out it has a default free shipping for all subscriptions. There are no active codes for it. I have reached out to the app and they said its a shopify issue. Any thoughts on how to change this so it uses the shipping profiles I have made? Its mind boggling as it is no where on my admin side that has it listed, yet it has it at checkout and does not list any other rates I have set.
