Standard action are being added to unified audit policy

Good Day all,

running Oracle Database 19c Enterprise Edition Release Version 19.27.0.0.0

I have a custom unified audit policy that audits all actions except SELECT/READ on application object by backend users. When I updated the policy when a new object is added it will automatically add INSERT, UPDATE, ALTER TABLE ,DELETE

Before I run the update
POLICY_NAME AUDIT_CONDITION AUDIT_OPTION

UNI_POL NONE GRANT

— run update
ALTER AUDIT POLICY UNI_POL ADD ACTIONS ALTER TABLE, DELETE, INSERT, GRANT, UPDATE, RENAME ON TESTER1.MV_TEST1;
ALTER AUDIT POLICY UNI_POL ADD ACTIONS DELETE, INSERT, GRANT, UPDATE ON TESTER1.VW_TEST1;
