EI factor is calculating wrong rate, overcalculating employer expense

SOLVED

I received a PIER review from CRA for the 2019 T4 filing. The discrepancy was with Employer portion of EI premiums, after much searching and troubleshooting to figure WHY it was overcalculating the Employer's portion, I was able to figure this much out: Sage 50 is calculating the worker's EI amount correctly at 0.0162 of the gross earnings. The Employer's portion would be 1.4% of the worker's amount. But what is happening is it is actually taking 1.62% of the worker's EI calculation (so it's using 1.62% both times, instead of 1.62 for the worker and then 1.4 for the employer).

Example: Employee paid $1000, Sage calculates $16.20 in EI is owed by employee. The employer's portion should be $16.20 x 1.4 = $22.68. BUT Sage is instead doing $16.20 x 1.62 = $26.24. This results in a small overcalculation of the employer's EI expense and liabliity, resulting in my overpayment of EI in 2019.

My payroll settings are as follows:

For the Employees settings, under the Taxes tab for each infividual, the EI box is checked and set to calculate a rate of 1.62 for the worker (the 2019 rate)

For the Employer settings, under Setup>Settings>Payroll>Taxes, the EI FACTOR is set at 1.4

So why would it be using a factor of 1.62 instead? I have been using Simply/Sage for a very long time, did I miss a bulletin or something? Does that EI factor setting not work anymore? Do I have to go through every individual employee record and change the EI calc to 1.4? And if I DO THAT, how will Simply know what EI rate to use for the employee portion? Won't I just end up with same problem except on the worker's side instead? (which would be much much worse).

I would also like to note that this problem is still happening in 2020, and that in spite of current payroll taxes and updates, my EI rates and factor HAVE NOT been updated to the 2020 changes.

I can make a manual adjustment to correct our books to reconcile with what CRA says we owe, and will now have to re-submit amended T4 summary, but I need to fix this going forward as we are overpaying every month.
