Does anyone else notice sugar alcohols are not subtracted from the total Carbohydrates?

I made a Keto strawberry shake/smoothie and used Lakanto Sugar-Free Monkfruit Sweetener. Per teaspoon there are 4 G of carbohydrates. However, they are all sugar alcohol (4 G sugar alcohol). My understanding is that when you calculate Net Carbohydrates both fiber and sugar alcohols can be subtracted.
