Hi Kadubei,

can I ask you why you duplicate multilingual names in waterway ways that are already part of a waterway relation?

Such as here: https://www.openstreetmap.org/way/69904069/history
which is already part of this relation:
https://www.openstreetmap.org/relation/9612817/history

One of the main purposes of the waterways relations is precisely to avoid info duplication, I quote from the Wiki: "The purpose is to have only one element with all common informations about this watercourse (name in different languages, wikidata, wikipedia, ref, destination) instead of having these informations on each way (with probably some ways with missing informations)."
