So here is the picture: Sotre Listings (Languages support in package)
Why there are two Hungarian? I need to fill in everything twice! (like description, pictures etc...) What i need to do? Or its normal?
Actually the second one Hungarian (Hungary) is targeting on Hungarian market while the first one single Hungarian is for other country/region where people also speak Hungarian, like Romania. There are around 14 million people speaking Hungarian language. About 10 million of them live in Hungary and the rest 4 million spread over Romania, Czechoslovakia and Yugoslavia etc.
The counterpart, you might see in Store listing languages, is about Italian, Italian(Italy) and Italian(Switzerland). The second one targets on Italian market and the third one for Swiss market while the first Italian targets on the rest country/region where people mainly speak Italian.
Now you could complete the Store listing page by selecting language you want to support. More details, please refer to Store listing languages.
