All chocolate contains some carbs, 100% is just zero added sugar. However, not all 100% beans are the same so the amount will vary a little, usually somewhere between 10g and 13g per 100g of finished product.
I would complain to Hotel Chocolat and tell them to fix the labelling on the packages if they are still selling this with the wrong info (it appear they fixed the website nutritional info).
