Garmin Fenix 5x: bug save round-trip course

When you create a round-trip on your Garmin Fenix 5X and want to save it. The Fenix 5X try to make a .fit file. You have to reset your Fenix 5X fast otherwise you get a large fit file that does not work.

.

Select Navigation > Round-Trip Course.
Enter the total distance for the course. It does not matter how much
Select a direction heading. It does not matter what you choose
The device creates up to three courses.
