1031 exchange using QI exchange funds to credit buyer of downleg

[Susan O.]

We recently are doing a 1031 exchange and closed already.  We found out htat we were supposed to credit the buyers something on our sold property.  I was wondering if the QI could credit the buyers of our downleg property after the escrow has closed? It's sort of a mistake in the escrow but the QI seems to say it's OK to do but it's a gray area because it technically should have been handled in the escrow. So almost as if it's not a certain thing. Anyone know for sure had this experience?
