SOAP API RequestStatus does not return RecipientId

I have use case where I need to uniquely identify a recipient. With REST API, it works fine. However, with SOAP, response does not return RecipientId as documented.

https://demo.docusign.net/api/3.0/dsapi.asmx?op=RequestStatus

<RequestStatusResponse xmlns="http://www.docusign.net/API/3.0">      <RequestStatusResult>        <RecipientStatuses>          <RecipientStatus>            <Type>Signer or Agent or Editor or Intermediary or CarbonCopy or CertifiedDelivery or InPersonSigner or SigningHost</Type>            <Email>string</Email>            <UserName>string</UserName>            <RoutingOrder>unsignedShort</RoutingOrder>            <Sent>dateTime</Sent>            <Delivered>dateTime</Delivered>            <Signed>dateTime</Signed>            <Declined>dateTime</Declined>            <DeclineReason>string</DeclineReason>            <AutoRespondedReason>string</AutoRespondedReason>            <Status>Created or Sent or Delivered or Signed or Declined or Completed or FaxPending or AutoResponded</Status>            <RecipientIPAddress>string</RecipientIPAddress>            <ClientUserId>string</ClientUserId>            <AutoNavigation>boolean</AutoNavigation>            <IDCheckInformation xsi:nil="true" />            <RecipientAuthenticationStatus xsi:nil="true" />            <CustomFields xsi:nil="true" />            <TabStatuses xsi:nil="true" />            <RecipientAttachment xsi:nil="true" />            <AccountStatus>string</AccountStatus>            <EsignAgreementInformation xsi:nil="true" />            <FormData xsi:nil="true" />            <RecipientId>string</RecipientId>            <DeliveryMethod>Email or Fax</DeliveryMethod>            <FaxNumber>string</FaxNumber>          </RecipientStatus>

Is this a bug where RecipientId is not being returned in RequestStatusResponse?

Thanks in advance for your feedback
