Build SP: problème avec la notification d'une page marked for delete avec une sous-page en nstep

Créé une page dans ma topbar avec le user Steven (RWA depuis la home). il y a une sous-page en Nstep dans mon left menu attribué à John et Raoul. Le tout est validé puis la section effacé (similaire à min-289)

Si je tente de passer ma page avec mon user steven depuis la home en notification (jaune), cela me fait une belle exception:
