All that is is the position keep lock. It just holds the data on the last solution you entered, it will update accordingly. Your just seeing it different because its not a big red lock button.
HENCE TDC ON / OFF, it adds the dreaded triangle now but all you need to do is remove the image from your data folder and its gone ;]
Now if you turn it off you get the data screen again where you can update manually....
And NO your not changing realism settings in the game.................
