The organisation that is responsible for naming roads is the municipality, and each municipality registers their street names in the BAG registry. If you look up this street in the BAG ( https://bagviewer.kadaster.nl/ ), select the BGT layer (BRT is outdated municipalities indicated), then the road name shown is here "Schaloens Molenweg". In the past few years I noticed that commercial map websites have dozens of errors on their maps, so just basing on them is risky. In this case Google Maps also says "Schaloens Molenweg".
