Please don’t create multiple notes for one problem. One note is sufficient.
Please remember that OpenStreetMap is first and foremost a database. Not a map!!!
The map that you see on the OpenStreetMap.org website is ONLY ONE variation of displaying our database as a map. And we as mappers are not even responsible for that! There are different developers for different mal styles. Every map style shows different things, and almost all of them never show every object that is in the database so it does not clutter the view. So if some villages he in Bad Münstereifel are not shown at different zoom levels, this is correct and the decision of the map style developers, not with the data in our database. You can even switch between different map styles on the right side menu with the 3 layers icon, every style looks different. If you don’t like the visualisation, please don’t create a note here. Click the little info-i next to the map styles which leads you to more infos to this style and probably a GitHub page where you can raise requests.
And finally I don’t understand why the hell you created these notes here in Bad Münstereifel. This happens to every village worldwide at that zoom level. I will never understand …
