If you spot errors, contact your local municipality, since they provide this data to the central registry.
I'm not going to correct it, because it doesn't matter.
It does matter (although it is possible you simply don't care). This data is used for a lot of purposes, which may include the calculation of your house's estimated worth for taxation.
Most municipalities do appreciate the feedback via https://bagviewer.kadaster.nl. A more accurate public dataset benefits society as a whole.
Strange thing is, they're inconsistent about it. De 1914 building De Vereeniging is listed as 1914 even though they've at the very least added a large conservatory to it since as well as a humongous - and very ugly and cheap looking - backstage area (though that was only this year, so maybe that hasn't ended up in the data set yet).
Oh well ...
