 Earlier i did retrieved same updateset from test instance but unfortunately i deleted update source but that retrieved updates still in  retrieved update set table in preview state with update source is empty ok. I created new update source to tried retrieve test instance update sets again . It is already retrieved in first time with old update source  That's why retrieved update set tab is not visible in new update set source because it is already retrived. So I went back to retrieved update set table deleted retrieved update sets   state is preview update source empty.Now it is showing latest update sets
