Nutriscore is not computed due to missing nutrition, while nutrition info is available

On this product: https://fr.openfoodfacts.org/produit/8003170057777/orzo-solubile-biologico-conad?rev=80,
nutrition information is available, but the Nutri-score is not computed due to missing nutrition information:

Les données nutritionnelles du produit doivent être spécifiées afin de calculer le Nutri-Score.
Informations nutritionnelles manquantes : Énergie, Matières grasses, Protéines, Acides gras saturés, Sodium, Sucres

We're expecting the Nutri-score to be computed if all nutrition information are available.

@raphael0202 It's because it's a product that needs to be prepared, and the nutrition facts we have are for the product as sold.
