Yeah my guess is the real time one as well.
The average one has a circle with a line through it next to the value to denote an average value. The real time one goes up and down and you press the accelerator. If you lift off completely it goes to ---mpg

You need to press and hold 'ok' until the reading flashes and then it will change.

The other thing to check is whether there's a little 1 or 2 in the top corner.
1 is the current values, 2 is the averages since the car was made (or at least the last 10k miles or so).

Btw you can reset the 2nd set of averages, distance, speed etc by pressing and holding the OK button on wheel. 1 seems to reset after a few hours of the engine being off
