Thank you for contacting WPML support, I'd be happy to help you with this issue.
I use the Inspect tool of the browser and see the space under the paragraph is a "div" tag and a single space character " ", screenshot hidden link
The single space character is not sent to the Advanced Translation Editor so it won't display on the translation page and causes the issue. This is a known issue and has been escalated to our development team to fix it.
You can use the breakline tag on the original page or manually edit the translation page and add the line break.
I have seen very many posts regarding these kind of issues. Is there somewhere we can follow the progress of this bug? When is it estimated to be fixed? As that would save us plenty of time.
Sorry, I cannot give you the estimated time to arrive. But this issue has been escalated to our development team and I will update you here when I have any information.
