Winner audio message is not always correct at the end of race

[GRUNZ]

I have noticed several times that when a (endurance) race is finished, the audio message of the winner ID is most of the times wrong.
Last weekend I noticed why it was most of time times (sometimes it would get it correctly)...Basically the audio message will announce as winner the ID of the car that last pass over the S/F line. With last I do not mean the last position I mean the last car that will conclude the last lap before the race is over. If it happens that is the car that has the most of the laps (basically the winner) then it would be the correct announcement. But most of the times is not.

I am not sure that this happens in GP mode as I have not raced in this mode for a very long time.
