Amul sugar free dark chocolate has misleading nutrition..

So I recently started getting advices to have anti inflammatory food for weightloss, and i have been having somethings like bell peppers, spinach, brocolli, mushrooms, tomatos, turmeric with lemon in hot water etc. also heard that dark chocolate is also anti inflammatory. So bought amul sugar free dark chocolate cause it has lesser calories than normal, and I am have a no sugar diet(not even fruits). But to my annoyance, the pack says it's 558 calories per 100 gms despite showing 475 every where online. What is this scam?
