List of steps to reproduce (step by step, including full links if applicable):
- Map where I noticed this https://pt.wikipedia.org/w/index.php?title=Inc%C3%AAndio_florestal_de_Pedr%C3%B3g%C3%A3o_Grande_em_2017&curid=5446792&diff=61400792&oldid=61245839&diffmode=source#/map/1
- Same map on Commons with correct label: https://commons.wikimedia.org/wiki/Data:Portugal%2FIncendios%2F2017%2FPedrog%C3%A3o.map
What happens?:
Wikimedia map layer shows Serbian name for Portugal ("Portugalija" – "name:sr-Latn" key value from label node 2377028247) instead of the Portuguese or even English ("Portugal"). Other labels seem to be ok, such as the one for Spain, correctly shown as "Espanha". The error doesn't show on Wikimedia Commons.
What should have happened instead?:
The label for Portugal should be "Portugal".
