Aatrix won't file my form 940. It pulled in a negative .02 for the 4th Quarter 2016.

Aatrix  pulled in a negative .02 for the 4th Quarter 2016 on my 940.  It won't let me file with a negative number there, and it won't let me edit the 4th quarter.  Any advice on how to correct? It says to update information in my accounting/payroll software.
