i think i understand. In fact you added name:eu because you saw  this name around roundabout, isn't it ? 

but it's wrong name, this name=eu=* are only description, it's not a name.

there's a contributor who like to put some name:eu=* which are not name but description, i try to clean it.

and i saw this https://osmose.openstreetmap.fr/fr/map/#loc=16/43.314927/-1.350481&item=5060&level=1&fixable=josm

thanks to your reply
