Bug: Sales notifications are shown twice

Hi there,
first of all thanks for a great light-weight sales notification plugin!
However, there’s one issue I found. If a website is using a multi vendor plugin such as Dokan, WCMp, WC Vendors or others, WooCommerce creates parent and sub orders in the order section. Your plugin shows both types of orders, so every sales notification shows up twice, unfortunately. Could you fix this please?

Furthermore, you can only choose between random and recent orders which is great but, random orders seem to show every order that was ever placed while the setting recent orders only shows the latest orders but always in the same order. Is it possible to randomize the “recent orders” setting or set a date range for the “random” orders setting? Thank you very much in advance.

Best regards
Lars
