@rinigus: Please correct me, if I'm wrong... I guess, GPX (smart) import of PM is mainly designed for importing waypoints instead of tracks. If you import GPX with multiple waypoints using "GPX smart", PM will try to create a route connecting all waypoints (as long the waypoint coordinates can be referenced to streets within the used maps). If you import GPX with multiple waypoints using "GPX" PM will connect the waypints directly (without routing between them and turn-by-turn announcements). BTW: This is actually the only way to create routes with multiple stops (without possibility to edit these within PM).
