Sounds easy but it isn't. QLGT does not know that the one polyline is the same as the other one. It's just a line and at the end of the line it does not really know how to proceed and what line nearby is the right one to follow. E.g. take a road that leads into a channel. If QLGT uses the closest polyline it would add the channel to the path. To solve these problems the Garmin format adds routing information that helps the routing algorithm to follow the polylines that form a road. However QLGT does not extract this information. Thus it's blind and can't go on at this point.
