Vin scratch contracts

Not sure what is intended but when you purchase a vin scratch contract and it is store in your laptop the cost to do the contract says "0" crypto but when you go to do the contract it charges you the crypto for whatever class it is. This threw me off as I wasn't expecting to have to pay to do the boost didn't have the 400 SVC. I wasn't able to do it the vin scratch because of it. Either way it doesn't matter if you need to pay or not to do the boost but it should tell you that the contract cost SVC to do before you go and try to do it.
