Translation Issue

Helly guys, this plugin works nice and i am very satisfied with it.
But the problem is, that some words can not be translated.

I use german translation which you can find in: wp-content > languages > plugins > name-directory-de_DE.mo and .po. The file are 100% translated, but on the wordpress page some words are not translatable. The question is why?

As example not translatable files:

1) Back to
2) Submit a
3) There are currently ….. in this directory

Can you check your files to see why in other languages its not translatable? I use the latest version.

I would be very happy to translate these 3 words. Thank you in advanced Sir!
