Hey there, @pipoulito!
Thanks for contacting WooCommerce.com Support. In order to further assess the reason for Failed orders still processing payments successfully, I’d first like to take a look at your Stripe logs. They’re located in the WooCommerce -> Status -> Logs area of your site. Preferably, we’d like to see Stripe logs from the date that your most recently affected order was processed. Since these logs can contain sensitive information from your customers, I suggest creating a ticket with us so that we can review that information. Please, don’t post your logs here in the public forum. When you create your ticket, be sure to include the link to this forum thread, so we can pick up where we’ve left off.
