Twitter help/languages

language

#1

33 Languages are getting returned along with their language code using GET https://api.twitter.com/1.1/help/languages.json where as in https://twitter.com/settings/account 48 languages are available
Why the other 15 (48 Available Twitter languages from Account settings-33 returning from help/languages API) languages are not returning using the above API

And some language code excluding ‘Und’ ,language codes like ‘ta’ -> Tamil are being returned from Tweet object but the ‘ta’ is not present in help/languages

Some one please explain the reason and Solution for this
