Attached is a sheet metal bend screen shot.  I am unsure why it will not allow this sketched bend.  The error just says error performing the sketched bend.  I obviously only want to bend the small flange.  I have all the actual necessary settings plugged into the property manager to the side I am using for the bend.  It is .125 thick material.  I used the exact same setting on all the other bends on this part.  I am assuming it is due to the this flange and the relief cutout in it.  I tried bending it from both sides of the part.  Any help?
