Reprend #3251 et le ticket associé.

Si j'ai bien suivi, cela corrige un soucis d'enregistrement des dénombrements dans certains cas bien particuliers.
Mais si on corrige le soucis de saisie, il faudrait aussi voir si on peut aussi corriger les anciennes données erronées, éventuellement en utilisant la table d'historisation des contenus.
