I raised this to the attention of the OSM Tagging mailing list: https://lists.openstreetmap.org/pipermail/tagging/2018-January/034974.html. There may be an easy way out, but we'd need to understand how it works at your side, so I'd like to ask you join the discussion there to expose the problem you're facing and see how we can resolve it.

As a courtesy and awaiting your input to clarify the issue, I re-created a node with the shop information: node/5355126785.

Typo: before -> because

Not findable by whom and where ? I'm asking before it's findable in OpenStreetMap.org: osm.org/search?query=Mons%20ICI%20Paris%20XL#map=19/50.45646/3.93246. I'm asking also because mapping a shop as area is preferred over mapping it as a node because an area can capture the entire surface where the commercial activity is conducted (e.g. the terrasse of a pub) which a node cannot represent. See the Buildings paragraph in the Wiki page on Shops: osm.wiki/Shops#Buildings. I'd like to better understand the issue you're experiencing because I wouldn't like to be constrained in mapping places more accurately based on a problem I don't understand.

Done. Thx.
