Yes, that's a known issue, but haven't figured out what actually causing it.
For me it works if ANRB SW ist started during a teamviewer session. The session has to be finished after SW is up and running. Teamviewer is changing styles to windows classic during session and back to windows aero. After that switching I've got these outdated flights in the list and on the map.
Second way to get it. SW is up and running and a fast user switch is performed. Second user uses othe style with bigger text and icons. After switching back to account with running ANRB SW I often get the "freezed" entries in the list.
