Tyre mapping program

I've been playing with this program trying to create a route and then sending it to my Garmin. The route is easy to manipulate, but then when I send it to my Garmin the route is not the changes. Then I found that when I send the route back to Tyre, the route is the one I originally created. Does anyone use this program and can help in answering some questions?
