I selected an extraction file and clicked on "Open" in ribbon. The description was the following (see screenshot)

Same for cancel button.
Same when I am in the tool displaying all extraction files

Either remove the additional description, or handle another additional description, or rewrite it by being more generic (such as "Ce bouton est désactivé car aucun fichier d'extraction n'est sélectionné ou aucune modification n'a été apportée")
