Hello,

These are not building markers, these are address points. These do not imply that there are actual buildings. They are from official data, so they are "correct" even if the properties have not been properly updated in the official cadastral database.

You also removed nodes from buildings that still exist on the Northwestern side (unless all the private houses were also demolished? I don't believe so).

This data is also imported by an automated bot, so there's no point manually editing these points because they will get updated and overwritten anyway.

I undid your edit for now.
