Billing Cardholder Name is a required field.

Hello @taito

 This isn’t a default field in WooCommerce, so its appearance is likely due to custom fields.

Please check if there are plugins adding additional or custom fields to the checkout page.

You could also share a link to your site where we can test for this issue.
