Hi MarAurPer,
this changeset has created duplicate nodes by adding a bus route overlapping normal highways:

https://tools.geofabrik.de/osmi/?view=geometry&lon=-75.55615&lat=20.37382&zoom=13&baselayer=Geofabrik%20Standard&overlays=self_intersection_ways%2Cself_intersection_points%2Csingle_node_in_way%2Cduplicate_node_in_way

Can you please fix this?

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

Kind regards
