I wanted to create an islet into a lake, but, after adding to my islet its name, place and relation to the multipolygone as “inner” (“outer” for the lake), and after waiting enough time to regenerate the map, it displays my islet like it was under the water. I’ve put (I think) the exact same parameters than another island somewhere else that appears correctly.
What did I do wrong ?

Thanks for your help !
