What should I do with an error message saying, "When the delivery type is selected as 'Not Free', conditional free shipping will be 0 KRW"?

This message returns when you choose delivery type as "Not Free" and input free shipping thresholds. 

Please set "freeShipOverAmount" as 0 KRW. 

<Delivery Type>

- Initial shipping fee on return (deliveryChargeOnReturn): Customer-borne delivery fees on return for free shipped products whose initial delivery fees were borne by the seller. 
- Delivery Fee on Return (returnCharge): One-way delivery fees on return 
- Basic delivery Fee (deliveryCharge): Customer-borne delivery fees for conditional free shipping 

* Note:
Above three are all one-way delivery only, and you should set the delivery fees in accordance with the delivery fee criteria. 

 

<For free shipping>
- Set the amounts for Initial Shipping Fee on Return and Delivery Fee on Return.
