wrong route navigation

Today i went running for a nice 20 km run. Planned out a route using Strava. 

Used my Epix gen 2 for navigation. While running i constantly had the maps on the screen. 

I completely followd the route.  At one point i recognized the point as passed earlier. 

The navigation brought me back to the start, not following the planned route. 

Did i do something wrong? Or is the GPX broken?
