I've changed the tracktype of a track from grade2 to grade1 since it is paved. However, on the map (osm.org/?lat=47.87241&lon=11.68913&zoom=17&layers=B000FTF) still a short segment of the track is rendered like grade2. Looking at the data I can not see the reason for this, the whole track should be grade1. Can anybody tell me what's wrong here?
