I'm confused about the "View Current Reservation" display for my waitlisted upgrade. The times and miles do not add up correctly. Has anyone else seen this odd behavior?

I'm booked on the following:
EWR-BRS (3,374 miles, 6h 45m)
LGW-IAD (4,853 miles, 10h 30m) (waitlisted for upgrade).

The view current res. display has three flights listed, two entries for the LGW-IAD segment, the second being the waitlisted upgrade.

The total miles is 9,706, total time is 15h 30m ??? and I see:
---------------------
OnePass Members: Upon completion of this itinerary, you will earn up to 13,080 OnePass miles.*

Between the two LGW-IAD segments there is:

Change Planes. Connect time in London, England (LGW - Gatwick) is -30 mn.
