Google Play : Android Developer Console beta problem

Google had released a new beta version of Google play Android Developer console..
However, I get a problem when in providing multiple language description on my apps.

I defined 4 language description (English-US, English-EN, Trad Chinese & Simp. Chinese). It looks fine in new beta.
But when I switch back to old version. the language tag just show Eng-en x 3 & 1 x Trad Chinese.

I have reported the issue to Google, and see if they have any reply.
