Bad zone content in transfers

Are you using views on the master? This sure sounds like the classic "matching the wrong view" problem.

More generally, do you recognize the contents of the "wrong" version of the zone? I've never known BIND to simply fabricate zone data before. It must be getting the data from *somewhere*.

You could perhaps run a sniffer, e.g. tcpdump or snoop, to verify where the slave is getting the bad version of the zone.
