When Netfiling my return I get an error message and CRA won't accept the file as it is. Why won't the software fix the error?

I have a T4 slip with no income in box 14, but it shows tax deducted in box 22 and EI Premiums in box 18.  The error message is due to no income in box 14, however, the money earned is not supposed to be income on this T4.
