Hello @LTWWordpress,
Thanks for asking. 
Please add following CSS under Pro > Launch > Theme Options > CSS:
.woocommerce .quantity:before {content: "Quantity "; display: block; color: #272727; font-family: "Archivo Black",sans-serif; font-style: normal; font-weight: 400; font-size: 109.5%; line-height: 1.3;}
.woocommerce-checkout form .payment_methods label {font-size: 15px; font-family: "Archivo Black",sans-serif;}
.woocommerce-checkout #payment div.payment_box input.js-sv-wc-payment-gateway-credit-card-form-input[type="tel"], .woocommerce-checkout #payment div.payment_box input.js-sv-wc-payment-gateway-credit-card-form-input[type="text"], .woocommerce-checkout #payment div.payment_box input.js-sv-wc-payment-gateway-echeck-form-input[type="tel"], .woocommerce-checkout #payment div.payment_box input.js-sv-wc-payment-gateway-echeck-form-input[type="text"], #add_payment_method input.js-sv-wc-payment-gateway-credit-card-form-input[type="tel"], #add_payment_method input.js-sv-wc-payment-gateway-credit-card-form-input[type="text"], #add_payment_method input.js-sv-wc-payment-gateway-echeck-form-input[type="tel"], #add_payment_method input.js-sv-wc-payment-gateway-echeck-form-input[type="text"] {border-color: #ddd; background-color: #efefef; color: #000;}
It looks like for display Options total and grand total, you are using a 3rd Party Plugin WooCommerce Product Addons. Unfortunately we can’t provide customization services for 3rd party extensions that requires core level code changes as it falls outside scope of the support we offer.
Thanks.
