[Закрытые] ATE randomly adding Paragraphs to the translated page

Background of the issue:
I am trying to translate all subpages from German to English which worked well so far. Unfortunately, the ATE seems to split up what was one paragraph in the original language into multiple paragraphs randomly. This destroys the page formating throughout the whole website. Link to a page where the issue can be seen: скрытая ссылка

Symptoms:
Instead, the translated English paragraph is split up into multiple paragraphs, even though they are shown as one in the ATE. This issue applies to almost every subpage and occurs randomly.

Questions:
Why is the ATE randomly adding paragraphs to the translated page?
How can I ensure that the translated paragraphs match the original structure?
