Auto Trip- Adding last journey

OK- here's another thing that doesn't look like it works like it's supposed to on my '15. The trip computer has 3 modes. Auto, 1 and 2. the 'auto' mode resets every time you shut off the car. So, if you want to connect two legs of a trip, it has the capability to add the current stats to the previous trip by holding down the i button for 1 second. Up on the screen pops "Adding last journey". Except... mine never adds the prior mileage.

doesn't work. anyone else use this feature?

On a separate complaint note... it's very nice that you can select which trip computer variables to display. except they're missing a pretty important one. TIME! why the heck don't we get 'time' as an option?

update. I think it was user error. If I hold the button a little longer, it adds the previous journey. My fault.
