Hello Shake71, dear colleagues,

change set metadata suggest this edit was made using the app "maps.me" which allows editing POIs. Sadly, there are frequently users of this app that misunderstand the feature "add X to map" as a personal note book feature when in reality this will add the POI to the database of OpenStreetMap. A database used by millions of people every day.
Also, maps.me data is always way older than the information stored in the database at any given time. So sometimes people don't see a POI they are adding in their app while it's already there in the database.

Shake71, should you wish to contribute to OpenStreetMap you're more than welcome to do so. Please choose a different app for that.

Should you have any questions: We're more than happy to help. Check out the chat possibilities here
