Philadelphia local tax

 I have no amount in my 2024 W2 box 18 for Local Wages, tips, etc..? I have an amount in box 19-Local Income tax (Philadelphia) but box 18 is blank and the tax software keeps saying that box 19 cannot equal or exceed box 18. The box is blank on my W2. I live in NJ and pay NJ taxes. First time in last 7 years this has happened. What should I do?
