Language Copy Issue

Hi Team , 

I have my content structure as below . Let's say when i try to do language copy for Test Page to specific locale zh , i dont see Chinese option rather i could see something different language Aragonese. While debbuging I just noticed if i change to an folder 'aen' or something , then i could see the corresponding Chinese language displayed in language copy console . Please advise if I could not have my root folder as 'an' 

/content/an/abc/language/en/index

/content/an/abc/language/zh
