[Решено] Automated translations separate each line in a paragraph

Background of the issue:
Hello

Lately, translation of entire paragraphs was activated. Great. Unfortunately, after translating a paragraph, each sentence is written back with a line break. Paragraphs are thus no longer proper text blocks. Is this a setting (where?) or possibly a bug?

Regards
Karsten

Symptoms:
Automated translations appear with linebreaks after each sentence within paragraphs.

Questions:
Is this a setting or possibly a bug? I have the same issue on multiple sites.
