Hi, I will try to explain that correctly.
Currently our (mapy.cz) renderer ignores the 'superroute' (or the parent relations, as mentioned in previous messages), so only the child routes are rendered, so only the ref (16 in this (https://www.openstreetmap.org/relation/1128459/history) case) were shown in our map.

So I copied the name from parent relation to child relations to 'fix' this issue as the names of 'simple' relations are rendered on our map.

You proposed, that using (by the renderer) only the parent relation (and ignoring the child relations) will solve this problem in better way (no need to copy name from parent to child -> no need of editing at all). We will try adopt this way of processing those relations.

Hope I explained it well. If not (and if you are still interested in this discussion), ask me.
