Hi Violaine_Do,

I have seen on couple of your changesets that you are changing boundary=land_area to boundary=administrative. 

The problem that is happening is that now we have 2 relations for the same administrative unit, one with just land area and another one including water area. 

Is there any consensus withing community about how admin_level=6 boundaries should be represented on OSM?

If there is one, can you, please, remove duplicate boundaries?

One of the examples of duplicate boundaries:
