Problem with setting the point with "plannedHomePosition"

Hi all, apologize for eventual double posting the same question.

I would like to test the following simple .plan file below and exploit the option “plannedHomePosition” to directly set the starting point but after uploading it with the option plan>storage> Open…

it tells that the first waypoint is too far away, even if the parameter “plannedHomePosition” is sufficiently close.

Do you know what am I doing wrong?
