It sounds like you may have listed your partner in the software and tried to remove him but NJ still sees him, and the number of exemptions do not match. You may need to go back to the Personal Information section.
Below is from the NJ instructions line 6:
Exemptions – Lines 6–12 Fill in the ovals that apply. For each line, enter a total in the boxes to the right and complete the calculation. The number of exemptions you are claiming must be entered in the boxes or the exemption(s) will be disallowed. The number of ovals filled in must equal the number of exemptions claimed. Line 6 – Regular Exemptions You can claim a $1,000 exemption for yourself and your spouse/CU partner (if filing a joint return) or your Domestic Partner. Note: The domestic partnership must be registered in New Jersey by the last day of the tax year. You can only claim your domestic partner if they do not file a New Jersey return. You must enclose a copy of your Certificate of Domestic Partnership the first time you claim the exemption.
