Editing OSM map and not displaying it

Hello
I edited the map and added a historical complication to the map a few days ago, why won’t OSM show it?

OpenStreetMap

maybe see the OSM wiki about

I_have_just_made_some_changes_to_the_map._How_do_I_get_to_see_my_changes?

If you’re referring to this node, I think it lacks a building=yes tag.
