Round-trip Routing - saved courses are shorter than calculated ones

Hi,

I was playing around with Round-trip Routing to see if my Fenix (5X APAC, ver 4.10) will be able to "discover" a new route in my area and I just discovered that only a small part of the generated course is saved to the FIT file. For example a watch is showing me a generated route about 44km long (a loop) but when this route is saved and I'm opening it in a Navigate only small part is displayed/visible - 6km, 10km, max 14km, and it always part of the created earlier loop. Does anyone else experienced similar problem?

Best Regards,
Mariusz
