Pay Rate Change file not converted correctly from pre-2018 to PR 2.20

Am testing a client who relies heavily on this file .  Have already found an issue re renumbering - doesn't appear the history follows the renumbered employee.  Now have also found that the conversion did not bring over the Date Changed field (this is CRITICAL) and the user who entered the data (my client doesn't care about this, but some may...).  Any one else confirm?
