EPF - service history from the Old UAN is not reflecting in the New UAN number

One of our employees had two UAN numbers. One from his previous employer and second from our employment. We applied for transfer from Old UAN to New UAN via online. The amount in the Old UAN account has been transferred to the new one. Now the problem is, the service history from the Old UAN is not reflecting in the New UAN number. Kindly suggest what can be done here.

Dear Mr Deepak, Service History is UAN Specific.Since, Transfer from Previous UAN (Previous Member ID) has already Completed, the details will be reflected in member EPF Pass Book.It is Perfect, Nothing to worry

So,if my EPF transfer is complete, but pre-UAN service history does not show up on Member portal, should I not worry about?
