Visual Composer loading wrong language

Hello!

We’re experiencing problems with WP Multilang and WP Bakery Visual Composer primarely in the backend of our WordPress page.

I’ll explain how the problem occurs:
0. We’re speaking about a page which was already made in German and English.
1. We edit the German language of a page and save.
2. Then we switch to the English mode to edit the English part of the page.
3. When we now open a text block in Visual Composer the German texts are written in the text block.

It seems like Visual Composer doesn’t load the texts properly. Do you have any help for this problem?
