Wrong route recording Fenix 5s

My Fenix 5S sometimes doesn't record the route correctly, the dist acne is right but route is a complete disaster, also all the statistics which are generated during the route are a mass, step length , cadence and vertical ratio are also wrong recorded during period it started the false route recording, are there more people who see this problem.?
I'm on the firmware version 20.00, and see this after a endurance run.
