I have the solution First of I found its easier to copy all the files into my theme directory.

  1. Create the theme directory


  2. Overwrite Checkout pages

  3. Copy web folder from default theme to your Magento_Checkout

  4. Edit Magento_Checkout/web/template/summary/ (totals & grand-total) remove code below from both files.

    <!-- ko if: isDisplayed() -->
    <!-- /ko -->
  5. Edit Magento_Checkout/web/js/view/shipping.js

    Find selectShippingMethod Function line 215 and add


    Should look like this

    selectShippingMethod: function (shippingMethod) {
        checkoutData.setSelectedShippingRate(shippingMethod.carrier_code + '_' + shippingMethod.method_code);
        return true;
  6. Run following commands

    php bin/magento setup:static-content:deploy
    php bin/magento indexer:reindex 
    php bin/magento cache:flush
