Incorrect Altitude Settings

Using MCE 2.6.67.

Problem with PMDG 747x, haven't tried any other aircraft.

Problem is repeatable, namely co pilot failing to dial correct altitude when commanded.

For example commanding altitude 22,000 feet using the words "altitude twenty two thousand" always results in co pilot setting altitude to 2200 despite command clearly being ecognized by red text.  If I use the words " flight level two two zero or "altitude two two thousand"  co pilot sets correct altitude.

Thanks.
