Understood.
Thanks for the fast answer.

Ok, I answer to myself.
The featured images is at the bottom left / “settings” (gear icon) and here you can change the page name and add a featured image.
It’s not in Elements / Single / Featured Image.
I did it, but it didn’t change anything.
I really start with wordpress, so, if there’re obvious stuff to do that I didn’t, you can tell me !
Best regards
JM
