How to update past employee enrollments after changing the rate configuration

Summary:

For a particular plan, employees contributed an incorrect amount due to an incorrect rounding rule. After updating the configuration and triggering the new life event, employees began contributing the correct amount. However, how can we correct the past contributions? Additionally, starting 1/1/2025, employees resumed contributing the same incorrect amount after the Open Enrollment (OE) event. How can we change this without voiding the OE life event?
