I’m running Magento v22.214.171.124 and the shipping cost is being doubled in the Grand Total on the shopping cart page as well as within checkout.
This happens regardless of whether tax is involved or not and regardless of shipping method (i.e. flat rate, FedEx, UPS).
I have searched the Magento forums and found that others are having the same problem. Unfortunately there are no replies with a resolution.
Would anyone here happen to know the cause or how to resolve this issue?
