On screen position over finnish line does not match race results

Just did Kiss100 race and came in on 2nd place accoring to screen but ended up in third in the results on Zwift post race result screen and zwiftpower.

The race ended with a custom finnishline on vulcano climb.

Hi you will get lag on sometimes I have finished 3rd and then found I have won depends on wifi sometimes

Dont think it was lag.
I was 10 meters ahead at least, sprinting uphill and the rider behind let up and I got several meters. I was way ahead on both my screen and on the screen of the rider who came behind me.
Its some kind of bug. It was on the Volcano.
I dont care very much about this result but I think this bug should be looked into.
