It seems that that Plugin Support is now pimping a purchased add-on product to WooCommerce as a solution to getting customer names with orders. I found this on another thread:

You appear to be correct in that the order CSV from the Analytics section only shows the type of customer.
To export full order details I suggest that you consider using:
https://woocommerce.com/products/ordercustomer-csv-export/
or similar.
A search for WooCommerce export orders details digs up some interesting alternatives as well.
I hope that helps you to figure it out.
Feel free to get back to us if you have further questions.
