Employment Insurance (EI) Employer portion not created when the Employee deduction is self-adjusted

In the Canadian payroll, every time an employee is deducted some Employment Insurance (EI) using Tax Area/Tax Type FEDERAL/CC, the system should always create an Employer-paid benefit (Tax Area/Tax Type = FEDERAL/CD) equivalent to 1.4 times the employee deduction or to the EI Employer reduced rate if any.  We have had three situations, each one involving a different employee where the EI employee deduction got self-adjusted therefore the FEDERAL/CC tax type ended up in a refund to the employee however no FEDERAL/CD tax type corresponding to 1.x times the amount refunded to the employee was generated .   JDE version 9.
