text: 8 administrative region unknown in population files of Eurostat, INE, even OSM refers to Wikipedia community Torres de Albánchez (relation 347988). We "assume" unpopulated area but a setting (i.e. population 0) would be helpful.
  According to the linked Wikipedia article, the exclave would be named "Cuarto del Madroño", the location description sounding fitting? Then this should be either have an Alt-name, be renamed or merged into 347988. The way it is now, I'm sure not being the only one loosing time trying to solve the riddle.
