OpenFietsKaart and streams

Hi
if you look at http://www.openfietskaart.nl/?zoom=15&lat=50.91404&lon=4.29276&layers=B0000TFFFFTT then you will see a stream marked as a regional cycle route eroneously. It’s not the first I’ve seen and yet not all streams suffer (I think it might be streams without names but I am really not sure)

I think someone has added a adm. boundary to a cycle route relation?
