How apple store determine languages information an application

Question

I have uploaded my app to apple store.
Everything is fine except the "Languages" in "Details" tab.
I don't know why many languages in my app's information. (see below picture).

1. is this setting in ituneconnect ? (I have only one localize in ituneconnect)
2. or somewhere in xcode ?

Answer 1

If you're using a library that includes localizations from certain languages, those languages will appear there as well, even though your entire app doesn't use those languages. Look for localization folders (.lproj) with strings files in them. This has happened to me in the past.

Answer 2

I believe this is based on the Localizations section in your Project Info tab
