Hi, everybody. I follow the tutorials, but I can not solve some problems. Can someone help me?

I have these questions:
1. Why some controls are not translated, how to translate these controls.
2. How to return to English interface.

The demo file is in the attachment.

I'm sorry, I was not careful enough, I did not create ".en.po" file, so I can't switch back to English,

I modify the contents of the control, realizes the control language switching.

Thanks.
