Hi pino zanda,
this changeset has created several errors in the OSM database regarding overlapping ways (blue markers):

https://tools.geofabrik.de/osmi/?view=routing&lon=9.14144&lat=39.94056&zoom=14&baselayer=Geofabrik%20Standard&overlays=duplicated_edges

https://overpass-api.de/achavi/?changeset=171623401

This kind of error irritates routing software and looks ugly on the maps. Can you please fix this?

You may also like to educate yourself about how to map hiking routes properly:
