I just got my z10 3 days ago and updated the os as well as updated twitter. I was cleaning house on the hub and deleted 15 twitter entries and about an hour later I got a hub notification and all the twitter feeds came back. I made sure I had the current version of twitter installed and restarted the phone. Deleted them again and they came right back an hour later. Any ideas as to how to get it to stop doing that as it is annoying.
