Le calcul du gabarit ('firstof') basé sur les valeurs supplémentaires des listes structurées utilise des valeurs invalidées lors du changement de la condition d'affichage des listes.

Il s'agit d'un problème avec les valeurs temporaires du système de substitution,
et il convient de nettoyer ces valeurs du cache avant de rentrer dans le workflow.
