Hi abebayehuz,
this changeset has left behind a lot of errors in the OSM database regarding self intersecting lines:

https://tools.geofabrik.de/osmi/?view=geometry&lon=38.84037&lat=8.99955&zoom=12&baselayer=Geofabrik%20Standard&overlays=self_intersection_ways%2Cself_intersection_points%2Csingle_node_in_way%2Cduplicate_node_in_way

It seems to me you tried to add a public transport line. Plse educate yourself about how this is properly done:
