[Jetpack + @xili] French comment form is not translated

[jazzyguy]

Hello,

On my WordPress website, the French comment form 'LAISSER UN COMMENTAIRE' is not translated when the English page is activated : see the two successive pages
https://tracesmusicales.fr/le-son-du-musicien/
https://tracesmusicales.fr/the-musician-sound/

(The languages are managed by the @xili plugins.)

Thank you in advance for your hints,
Guy ROBERT
