It’s possible that Naarderstraatweg wasn’t tagged properly at the time of the import ( Overpass Street Query ).
Another possibility, relating to the “part of a street is a bike path” issue, is that if the bike path portion of the street is not named the same as the street, then it will exist in CityStrides as a separate street (assuming that it’s tagged in a way that will allow it to import).
Basically, OSM doesn’t have “streets” it only has “segments” - so during my import I have to collect all of the individual segments and group them into a single street record. I do this based on the name tag. (This is also why there are sometimes two streets in one city with the same name, existing in CityStrides as a single street record)
