TUI Airlines Belgium and Thomsonfly

Hey,How come we can't track either TUI Airlines Belgium or Thomsonfly flights on FBOweb? The ICAO codes for them are TUB and TOM, respectively. I've tried for a while to track their flights but every time I try the tracker "No flights matching 'TOM%' were found in the database." But I know for certain that both of those airlines have flights on weekdays. Can anyone find a way around that or a fix for it? Thanks!Austin M.
