Incorrect Running Race Results

I was in a running race (WTRL Running League). The distance was 2km. My avg pace for 2km was 4:38/km. At the end of the 2km race I was prompted by Zwift to either leave the race course or stay on the race course. I chose to stay and walked another 530m. The results show my total km for the race to be 2.53 with an avg pace of 10:27/km which has put me in 5th position in Zwift Power. Why are the race results including the time spent walking after completion of the race? This doesn’t happen in a bike race. How do I correct these results?
