Uncomplete track after saving activity

Hello!

I have an issue with my fenix 5 plus. At some of my runs after the activity is saved the track has some kind of jumps from one place to another. Sometimes it's look like a bad GPS location for one second
But sometimes the track just jump from one location to another one at my course I just had. As you can see during that the laps are located correctly.
However its not always like so:

Looking forward if any have the same issue or how I can solve it.

Thanks
