For a project elsewhere I check all the streets of South Limburg (and look them up in OSM and BAG), and that the name doesn't appear happens so many times and found several bugs in the BAG website, about which I am communicating with the Kadaster. The BAG website is not just one map, but exists out of multiple layers coming from multiple sources. It is strongly recommended to me (by both municipalities and the Kadaster) to use the BGT layer and not to use the BRT layer, as that 2nd one has multiple errors and can be outdated. (Don't know why that is then the default layer.) The BGT layer should always be up-to-date, but still does not alsways show the streetname where it applies. Then the navigate to street via search box trick can help.
