Hi Felice,
this changeset has created a lot of errors in the OSM database regarding overlapping ways (blue markers):

https://tools.geofabrik.de/osmi/?view=routing&lon=16.47955&lat=40.64044&zoom=13&baselayer=Geofabrik%20Standard&overlays=duplicated_edges%2Cduplicated_edges%2Cduplicated_edges_areas

As yo may know, this kind of errors irritates routing software and looks ugly on the maps.
Can you please fix this?

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