I'm new to MRA so I tried a very simple route with just 2 waypoints, those being the beginning and the end. This was my first ever MRA route. MRA designed the route which looked fine. I then selected the route in Navigation and 2 routes were shown on the screen. The one that Navigation was asking me to follow was not the one that MRA had calculated. I decided to ignore the alternative route and follow the route that MRA had given. The route quickly adapted from the Navigation route to the one designed by MRA. It was not a problem but just a bit confusing. Have you got an explanation for this?
