It's because about the Chip of the device. I have the same problem, my device is in English, but Samsung Members changed to Spanish. If you have a chip on your device from a country that speaks Spanish as a native, you'll have the app on spanish. it's all on the chip to simplify the regions each member is in.
Me too, but we can't do anything. I hate everything they are publishing in the community because there is nothing productive or something that could help me if it happened to me, before I always read everything they published because it interested me, now I don't even want to enter the application.
