Perhaps they were using a graphical interface similar to Expedia?
You might need to escalate to someone using native Sabre or Amadeus (without the graphical mode).
It is unfortunate that most online booking site and graphical interfaces have a flaw that doesn't handle mixed class multi-city situations well.
See my post above (slightly changed while you were responding).
