Hi 0000FF berries,
Thanks for your answer!
I’m using Organic Map on my phone to edit OSM and there is not much editing possibility. I think I can’t see every tags and I cannot delete a place. 
Do you think it’s better to let a note like I did, or should I directly edit the map when I can access to a computer? For now I only have my phone and I just started with OSM so it’s not so easy for me do edit the map, I only do basic stuff.
