@AyeshaS1   It's a some part of operator record's instance key (DATA-ADMIN-OPERATOR-ID <IDofOperator>) so can you save as and create the new operator record with the correct ID? If it's production coordinate with operation teams before deleting the old operator record.

@AyeshaS1  The OperatorID is stored in the property pyUserIdentifier in the OperatorID page.

@AyeshaS1  You can delete and recreate with new name.
