“EN” indication next to subtitle label

Hi,

thanks for your plugin, I have been using it successfully so far!

I have issues with one minor detail though: I uploaded English and Spanish subtitles for the video I have on my homepage. To select the desired language, I click on the settings wheel in the bottom bar of the video. Next to both English and Spanish subtitles I see a square with “EN” written on it, which can be slightly confusing – shouldn’t this change based on the language, so that I have EN for English, ES for Spanish, and so on?

I tried to find a way to change it but I was not able to. Any help is greatly appreciated! ??
