missing i-1 suggestion on back V3.2.0

I am assigning the backbone residues of a protein using CCPNM V3.2.0.
No matter what I fill in the ``i-1 matches to show/i+1 matches to show (on backbone Assignment table), it will only show i+1 suggestions. I did all the backbone walk in one direction (i+1), but I cant do the other directions because when I select a residue it only suggests the i+1, not i-1.
Is there a setting that I am missing?


the main thing is that you need to start from an i-1 NmrResidue. Are you doing that?
