Hello, and welcome to OSM.

Proxy Delhaize Ma Campagne is already on the map.

I wish to raise your attention that "Organic Maps" is not recommended for OSM editing.  The main reason is because the data you see in that app often lags behind (weeks, possibly months).  We often have to remove duplicate objects added by users who believe that shops are missing.

Have a nice day.
