Hello,

The “Your order” is designed for not long titles (because by default we do not have “select” fields), in your case, they are long from the plugin therefore a scroll appears. If it does not fit you, you can use the below code in Theme Settings -> Custom CSS.

.woocommerce-shipping-totals.shipping {
	flex-direction: column;
	align-items: flex-start;
}

.woocommerce-shipping-totals.shipping td {
	width: 100%;
}

.woocommerce-shipping-totals .select2 {
	overflow: hidden;
}

Kind Regards
