Employee rate field is blank and cannot be changed after updating to Canadian Payroll version 8.0 PU 4

Under Payroll Employee on the Pay Tab the Employee Rate/Amt/Pct column for a rate based earning code displays a blank amount instead of the employee's wage rate.  It is not possible to enter an amount on this field.

However, this rate field displays an amount and can be changed on the employee's time card.

The rate field was able to be set on the employee pay tab prior to upgrading to version 8.0 PU4.  When an employee's rate changes, it shouldn't need to be adjusted on the time card every pay period.
