GLPCLOSE Year-end run created journals in next FY

We are currently using PS 9.1. Our FY is Apr-Mar.

The user had run the Year-End closing rule for a BU for FY - 2020 with As of date - 31/03/2021 on June 15 2021. The process is expected to create the YE journals with 31/03/2021 date. But instead the YE journals are created with 31/03/2022 date with FY as 2020 and accounting period 999.

I had checked the setup and everything seems fine. The CLOSE_DEFN_TBL.CLO_JRNL_DT_OPTN is R (which is default). Tried replicating the scenario in UAT environment with same parameters, the YE journals are generated with 31/03/2021 date.

Is there any reason due to which the Journals are created with 31/03/2022 date in PRD? Is there any setup i'm missing? pls help.
