I am using WooCommerce Subscription and One Page Checkout plugins.
I am able to unset billing first name and last name (and even set 'required' attribute to false, so both fields are successively removed from my One page checkout.
But when I fill all other fields and I place order, it displays a validation error notice: "Billing First Name and Last Name are required" and I am not really sure how to solve this problem?
Maybe it has been set again from some functions or so? How I can solve this?
