Hi, 
Please look here to see the many duplicated sections of path you've made:- https://tools.geofabrik.de/osmi/?view=routing&lon=43.39595&lat=14.55690&zoom=16&baselayer=Geofabrik%20Standard&overlays=duplicated_edges%2Cduplicated_edges%2Cduplicated_edges_areas

All the dark blue lines are your duplicated highways. Could you please correct your mapping and cease to duplicate highways in this manner?

Thanks.
