Bonjour,

êtes-vous francophone ? Dans le doute, je continue en anglais.

This changeset raises several points, among which:
 - the (longish) name improperly added to a path. Most paths have no name, it is the routes (in OSM, the relations) that have names.
 - the changeset has broken the continuity of the route relation, by adding a way at the end of the relation instead of at its rightful place. There exist means to avoid this, including ensuring that the relation is loaded in full in iD before editing it.
- as far as I can tell, the last person who edited the path that you now removed was... you 4 years ago :-)

I'll take care of fixing the route.
