List generates another order with completed status

The plugin gives a customer list where upon order creation, that order is copied. The copy has same product variations and same date as the original order, but with no customer id, and with a Completed status (instead of the status of the original order).

Here’s a screenshot of a variable product customer list: https://ibb.co/7Xst5S9

The copy has its own unique order number just after the original order.

I checked the orders from the WooCommerce orders page, there are no existing copied orders. Though the order numbers of the copied orders are skipped (e.g. Order # 13654 -> 13656 -> 13658 and so on). I had to disable displaying Completed orders to get rid of the copies from the list, but the order numbers still skip.
