I have two sales tax fields that show up. One is correctly defined in english.php as it shows up as "Sales Tax: $0.00". Functionally, it doesn't do anything, the value is always zero.
The 2nd field is not defined properly as it shows up during checkout as " : $x.xx". No verbiage. Functionally, it calculates sales tax correctly, and it only shows up during checkout if there is a taxable item in the cart.
I thought I had solved this problem a while back, but alas, no.

Any ideas where to begin troubleshooting this will be much appreciated

Thanks,
Audra
