I solved both problems : 1) in the ValueDescription, for the render, rendering, we need to use - osmcarto-rendering-area - osmcarto-rendering-area-size instead of - osmcarto-rendering - osmcarto-rendering-size but **only** if we need something : - for the [marsh][1] it is necessary to have these 2 lignes, - for the bare_rock, we don't need these 2 lines otherwise the rendering appears twice (I don't know why these differences). 2) in the ValueDescription, we don't need 'group=natural' otherwise the text stays in english. I don't try 'group=naturel' because with nothing it works so it is useless to add these parametersparameters [1]: https://wiki.openstreetmap.org/wiki/Tag:wetland%3Dmarsh
