Bug on Forerunner 965: (info has :distanceToDestination) always false

I tried to create an estimated total time (ETT) datafield based on the remaining distance. However, the "distanceToDestination" of the Activity.info does not work on my Forerunner 965. The expression (info has :distanceToDestination) is always false, even when activity is started and a navigation course is set. I expect this expression to be true, and the value info.distanceToDestination should return the value shown in the field "Navigation-Distance Remaining"  in meters.

The same happens for distanceToNextPoint, it should return the value shown in the field "Navigation-Distance To Next"  in meters.

In the simulator it works fine, once I start the activity with "Simulation - Activity Data - Start" and set a destination with "Simulation  - Set Navigation Data - Distance to (m) to 100 - OK"
