Hi Christian,
I put together a short route with 3 waypoints. As you can see from the video a new route is created by adding / moving / deleting a waypoint but the old route remains. You can see it clearly by changing the colour of the route - the old routes remain with the previous colour.
Reopening the route or loading a new route still displays the old route.
v2.28 and win10. Please note I get the same behaviour on different laptops
Quality of the video below is not great but a better quality from this link

Hope this is of help.
