Like the changeset comment says I did only combine ways and did do that only if they had before the same name.

But let me try to help, I checked houses around https://www.openstreetmap.org/way/6542475 and they all have addr:street=De Telgang

Also NWB show this road as Telgang, see https://app.pdok.nl/viewer/#x=177238.96&y=503327.49&z=12.3800&background=BRT-A%20standaard&layers=f2437a92-ddd3-4777-a1bc-fdf4b4a7fcb8;wegvakken

Also Bing Maps looks good to me: https://www.bing.com/maps/?cp=52.517182%7E5.715095&lvl=18.1

Can you share a link to BAG?
