What is your alternator doing?

Milton,
Why do your screenshots show 'Ign. Off' and '11.7V' yet also show alternator current draw?

Might be that the car hasn't gone to sleep and is still drawing power??

Maybe the alternator reading when the engine isn't running is showing the battery capacity that is available?

If the engine isn't running how on earth can the alternator have any output? It's rotated by the running engine to generate electricity.

Also the car is in 7 th gear and other gears so it is moving.

The ignition off symbol seems to be incorrect.

I've found the top menu bar voltage and IgN fields don't always work correctly in my IID with L322. The live value fields will be correct.

Just had a thought. They might be snapshots of a data log and taken after the fact.

I have wondered about this too. The top line of the display is not always accurate. Maybe if Patrick from GAP sees this thread he will comment.
We were definitely moving & the screenshot is live data taken by waving your hand across an Android phone thereby taking a screenshot.

Another screenshot on another day with the top line also confused:
