Before/After Values report in audit vault

Hi

I am wondering the Before/After Values report in audit vault console is empty even after making several update to the tables of HR schema. I expected the REDO collector will gather the data for this report. I have created capture rule for HR schema to trap both DDL and DML operations in audit vault console

The REDO collector status is up in audit vault console. I am using AMM to autotune the streams pool size, the global_names parameter is set to true. I have enabled supplemental logging on the table using statement:

ALTER TABLE hr.employees ADD SUPPLEMENTAL LOG DATA (PRIMARY KEY) COLUMNS;
