I assume you were connected over a different interface. It appears
that the code, which enables the reception of all packets hasn't
been called or is wrong. Currently you will see only packets that
are sent to the interface. Promiscous mode is also interesting,
but shouldn't have any importance in monitor mode, which the
iwconfig manual describes as passing all packets on the frequency.

I believe Jon Smirl reported the same bug. But I didn't quite
understand how to provoke it.
