I tested with a clean emacs configuration (as proposed in orgmode page
https://orgmode.org/manual/Feedback.html#Feedback) and it worked as it

I am sorry for not having done that at once. I'll do it next time.

Thank you for answering my question and I apologize again for not having
followed the recommendations

Best regards,

Xavier
