Please stop creating those useless notes!

ULB campus is a collection of multiple areas (which we call a "multipolygon").  Every normal map can show it normally.

You are apparently viewing OSM data through Organic Maps.  This is an app for mobile devices, they take OSM data and they make their own rendering of the map.

We have no control on the way Organic Maps does things.  And yes, they seem to produce a very strange rendering here, showing the university icon and the name on multiple places.

You created half a dozen notes to the main OSM website effectively blaming _us_ for creating "multiple duplicate data".  I wish to inform you this is misguided.  We are not to blame for problems with the way Organic Maps renders multipolygons.

It might be worth reporting this upstream.
