The problem in my mind, after reading the report, is that line crew didn’t have it in the front of their minds that the operating design of the system had recently changed.
The report doesn't state it but were line crews told that the CWS-P function had been disabled? If it was trained for in the initial type rating I would have thought that it was a procedure that was incorporated in the syllabus. If it wasn't a procedure then why was it part of the initial type rating?
