Original enrollment date is not overridden with Period start date formula

Summary:

There are two fast formulas regarding the calculation of waiting period. One is the waiting period formula and the other is Period start date formula with logic -the waiting period calculation should start from Pension adjusted service date and if it is blank then hire date.

Rehire Life event was processed to automatically enroll into a plan which should start from 1/3/2027. Then after few days, Pension adjusted service date was added to the employee and other life event is processed. According to the Pension adjusted service date, the enrollment should begin from 1/4/2025.

The Period start date formula is overriding the Coverage start and rate start dates as 1/4/2025 but the original enrollment date is still appear to be 1/3/2027 which is incorrect. How can i override the original enrollment date?
