Pot kurirjev in vezistov NOV Slovenije is not finished. See master route:
https://www.openstreetmap.org/relation/1658429
This master route needs to be sorted in order after importing all segments.
Once all segments would be imported, it's ment to rename segments - but during importing I saw helpfull to have segment id in name (I know, if we would have better tools or, tools that would combine ref +name when showing relation - this wouldn't ne neceserly. So just do it what you see it's better.
