K-1 interest income being taxed twice in NJ

I have a couple of K-1's which reported some gains in Part III box 2 and also a little bit interest income in Part III box 5.  The interest income gets reported in Schedule B and also in NJ-Bus-2.  It gets taxed once for interest and gets taxed second time at 50% in NJ-Bus-2.  Is there a way to adjust this so it will only be taxed once?
