The status of the orders changes by itself

Hi,
I have a big problem in WooCommerce/Orders: every time I change the “Status” of the order from “in progress” to “completed”, a few hours or 1 day later, it automatically changes back to “in progress”. Consequently, the customer receives one more time the email saying that the order is being prepared, even though he had received an email confirming that the package was sent… I have to do change the status back to “complete”. And then, it is ok, it doesn’t change anymore.
My website is in French so I am not sure of the exact translation in English of the status “en cours” (in progress) and “terminée” (completed) but I guess you understand the issue.
Many many thanks for your help.
Kind regards,
Fanny
