Waypoint sort does not work

Hi
I have observed a problem with waypoint sorting:
When setting Default waypoint sort to none than I would expect that the current sequence of waypoints remains unchanged.
After changing the sequence of waypoints with the Manage function using the up and down arrows I create a route showing the waypoints in the required sequence. However when going back to the Manage function to change the route the waypoints are sorted again by date.
I hope you can provide soon a solution for this problem.
Best Regards
