Need help with WooCommerce

I’ve enabled ‘Enable registration on the “Checkout” page’ in WooCommerce->Settings->Accounts-> Registration Options->Enable Registration. So now the option for account creation during checkout is visible but I’m facing an error.
During the checkout after I filled the both fields Account username and Account password and then proceeding to checkout it ‘s giving an error message ‘Please fill in the required fields’.
Please help
