New Media File not showing transcription all the time

the new feature Media File, under Media. I feed it an MP3 file in the Czech language. It starts off with the Czech transcript on the left and the English translation on the right.
After several line it begins to put the English translation on both the left and right.
Futher down the page, it again puts the Czech on the left and English on the right.
This pattern continues throughout the entire file. Part of the time, it gives the transcript and translation correctlly and part of the time, only the translation on both sides.

I am in the US

Podcasts are showing up just as they should. Czech transcription on the left and English translztion on the right.
