My Fenix 5x doesn’t show correct distance when I turn around at running track. I have two Garmin, I tested both on the same run. Fenix 5x always measures incorrect. How can I set my watch

I used vivoactive 3 on my right hand and fenix 5 x on my left Hand.. This is Fenix 5x’s map on Strava. It is always same. , same place same run two different map. First map is fenix 5x’s map. So how can I fix my fenix. Thank you
