Dynamic email using segmentation user language error

We have a dynamic email created which is segmented based on user language. We have updated the Korean version of the email with Korean text. There are 5 emails. When previewing via segmentation - user language = APJ Korean which is the template we updated for all 5 emails, only email 1 is showing in Korean. Plus, we also set up a smart campaign to test all 5 emails sending to my personal email where we changed my profile country to be south korea and user language to be KO and email 1 is received in Korean language and part of email 2 is, but the remainder are in english. Any ideas?
