Balance Adjustments are not capture to the get plan balance formula in the fast formula

I used the get_plan_balance function inside an accrual fast formula to capture the plan balance on different dates, but when I checked, it did not capture the adjustments that are done between the last accrual calculation date and the effective date.

eg: As of Feb 29, 2024 balance is 24 days, adjust 10 days to Feb 8, 2024. when I checked the balance from the get plan balance function it showed a calculated balance for the last date ( Feb 29, 2024) which means 24 days.

Please advise me on how to capture the adjustment amount between the two different dates.
