Problems using Bold Builder

Hey guys,
I need your help!
I’m trying to create a bilingual page on our website using the WordPress plugin Bold Builder. The final page should have 4 sections. I created the first for in German, hit update and automatically had 8 sections. When loading the page 4 sections showed up in each language. So far so good. After translating the last 4 sections again I suddenly hat 12 sections. The first 4 German ones appeared on the German site the 4 English and additional 4 German sections appeared on the English page.

I’ve tried everything I could think of and couldn’t find anything that actually helped so far on the internet.
So: what am I doing wrong?

Thanks in advance for any help!
