NJ State not allowing Commuter Transportation deduction for 2014. Employer did not show amount on W2, but deducted it from Federal Wages. Do I owe additional State tax?

State of NJ is not allowing Commuter Transportation Benefits deduction from 2014 income, says we owe taxes on the amount we deducted ($1,560). Employer did not indicate amount on W2, but deducted it from Federal Wages but not State Wages. Are they right that I owe the additional taxes (~$127)? Is it worth fighting?
