one one of the demo (will be added after task #121 is done), there is an extra serving unit quantity value when this code is used

$('#test7').nutritionLabel({
    showServingUnitQuantityTextbox : false,
    showServingWeightGrams : false,
    showIngredients : false,
    showServingsPerContainer : false,
    showItemName : false,

    textServingSize : 'Serving Size 6.96 10-inch pizza (3.7819g grams)',

    valueServingUnitQuantity : 9.3,

    showPolyFat : false,
    showMonoFat : false,
    showTransFat : false,
    showFibers : false,
    showVitaminD : false,
    showVitaminC : false,
    showCalcium : false,
    showIron : false,
    showCaffeine : false,

    valueCalories : 400,
    valueFatCalories : 220,

this is not really a bug as the test value is meant to be Serving size: so if this was used normally, it will show as Serving size: 9.3

so the problem is how we used this on the legacy desktop calculator of Nutritionix so we need different solution for this but this is not really a bug
