Unavailable to set language option to Korean

I don't have any options for switching in-game language to Korean.

Steam, EA app and basically any other sellers inform that Korean is supported in BFV, but there's no option at all in EA app to set game language to Korean for BFV.

I don't have any VPN turned on, and pretty sure that my region is set to Korea (I played the game in Korean without a problem back in Origin days) so I wonder what's causing this problem 

Edit: I tried installing Battlefield 4 to see if this is a universal issue, but I had no problems installing and playing with the language set to Korean. Seems like it's the problem of BFV alone.

Korean should be in between Italian (이탈리아어) and Polish (폴란드어) but there's nothing in between them but Japanese (일본어)!
