Hi helicoysfh_Plateau_import,
your recent import activities have left behind several errors regarding self intersecting ways:

https://tools.geofabrik.de/osmi/?view=geometry&lon=137.06146&lat=34.90160&zoom=14&baselayer=Geofabrik%20Standard&overlays=self_intersection_ways%2Cself_intersection_points%2Csingle_node_in_way%2Cduplicate_node_in_way

Can you please fix this?
Kind regards
Guido
