Welcome to OSM! You have created several problems with your first amendment. First, you try to keep your changes within a small range. Then you used the Location key to mark a skin entrance. The Location key indicates, for example, whether a hydrant is placed on the street or on the green next to the street. An entrance is marked with a dot and the key entrance, if it is the main entrance the tag entrance=main is used. By the way, such indications can be found documented in wiki.osm.org. The coffee shop can also be set as a point.
