I tried to edit the English label (to remove the bit in brackets) on https://www.wikidata.org/wiki/Q15869633 but it gives an error claiming that https://www.wikidata.org/wiki/Q138280 has the same description, when it doesn't.
The exact error message: Item Q138280 already has label "Alaşehir" associated with language code en, using the same description text.
