Achivements For Ardashir City

I been trying get final achivement for Ardashir city. The Race one I have used even timer to see if is me don’t make in time. But i have. Another strange thing happening that 20 sec into race give warning that i only have 30 sec complete. Even seems timer is off as well. if is 80 sec to complete race by timers race is not working for me. All other Races i have done and finish one in Ardashir is one not working.
