But it cannot be considered as a ghost update since the medical status has changed. Ghost update means that all infos remain the same even though it says profile updated.Ignore the agent. Your SS is complete. Those agents, depending on who you speak to might not know where to look. As far as trends have shown, if one has been in SS and gets ghost update, SS is complete. You just have to wait for an officer to come round to review and initiate re-med request.
I think it is a good sign though
