Tax Keeps Applying to Shipping

Hello! I am trying to set up a WooCommerce shop for my friend.
We don’t want tax to apply to shipping costs.

I hit save but every time I clear the cache, the New Carlisle row (with shipping checked) keeps reappearing. We only need the Gatineau row without shipping included in taxes. What am I doing wrong?
