Calores in a Tic Tac

So - this is a real question. How many calories are there in a tic tac?
The packet says that each box contains 15g. It also says that there is 390kcal per 100g. But it also says there is 2 calories per tic tac.
Here comes the crunch.
390kcal = 390000 calories
which means there is
3900 calories per gram
so there is 58,500 calories per 15g (or 58.5kcal)
Which means that there has to be 29250 tic tacs per packet for there to be 2 calories per tic tac.
Can you explain this anyone?
