This is actually the first time I really noticed this. In the tech tree, there is a special symbol that marks each unique technology. This symbol, however, displays the wrong race and tooltip.

I started a game as the Korath. Then a new game (without quitting), as Torians. Torian techs were there, but showed the Korath symbol and the tooltip read "Korath Clan". Next up, Terrans. They displayed the Arcean symbol and tooltip.

Looks like something doesn't get refreshed properly when starting a new game.
