Error displayed on checkout page

Hello, thanks for the great Leto theme
However, I discovered a small error at the checkout page. A small check box appears and I don’t know how to remove it. Please help me remove it

Hello there,

It looks like it’s a minor CSS bug that won’t affect checkout system of WooCommerce. To fix it, add this few lines of CSS code to Appearance > Customize > Additional CSS from dashboard.

    .woocommerce form .form-row .woocommerce-form__label-for-checkbox span.required:before, 
    .woocommerce form .woocommerce-form__label-for-checkbox span.required:before {
      display: none;
