Having some real issues with the Tax summary on Checkout/MyCart.
In Admin > Config > Tax > Calc Settings > Shipping Prices = INCLUDING TAX
I do a flat rate of $8.00 including tax, and our tax rate is 12.5%.
On Checkout, I have this mysterious 89c added to the Tax bill, which is the Tax already included in the Shipping.
Can’t figure out how/why this is be re-added.
