How to Change Total with VAT on email nvoice

I want to change the part of the customer email to Total and not Total with VAT (in USA).

I looked in the Language file at this part which deals with customer emails. I removed the "Total with VAT" to "" and it remained in the email. What do I need to change from the original below:

YOUR_ORDER="Your order"
SUMMARY_OF_YOUR_ORDER="Summary of your order"
TOTAL_WITHOUT_VAT="TOTAL without TAX : %s"
TOTAL_WITH_VAT="TOTAL with TAX : %s"
ORDER_TOTAL_WITHOUT_VAT="TOTAL without VAT"
ORDER_TOTAL_WITH_VAT="TOTAL with VAT"

Thanks
