As I check your JotForm, I see that the taxes are calculated for one service and the total is displaying correctly for it.
I notice that one service is added to exempt from taxes in the payment wizard and hence it shows zero taxes for one service.
You can remove this exemption from the Taxes section of payment wizard by accessing it through the wand icon on payment field of the wizard.
If you are referring to something else, please let us know. We will be happy to help.
