How to delete customers?

So… I have WooCommerce running on a multisite and ran a few test orders with PayPal Sandbox and fake names. I deleted those user accounts in the Users section but for some reason they’re still appearing in the “Customers” section, and I’m not seeing a Delete link there or any way to remove them. How do I delete Customers? I have also deleted the orders, so I don’t want anything at all in the Customers section because I haven’t launched the store yet.
