Drift lobbies.

To whoever can answer me this…

In an online drift lobby at the end of a race, it shows i am 1st on the scoreboard but when it comes to the podium screen sometimes i am not 1st, why is this?

I am aware the points you accumulate while drifting dont actually register until you have banked the points but even then I still seem to lose a place on the final scene of the podium.

Any help in why it does this?

Many thanks
