Problem:
You were experiencing an issue where adding translations of paragraphs and resaving them resulted in these paragraphs being overwritten with the text of the first paragraph in Classic Translation Editor(CTE).
Solution:
The issue was permanently fixed in WPML v4.7.2. We recommended updating all WPML plugins to the latest version after taking a full backup of your site.

If this solution does not apply to your case, or if it seems outdated, we highly recommend checking related known issues at https://wpml.org/known-issues/, verifying the version of the permanent fix, and confirming that you have installed the latest versions of themes and plugins. If the issue persists, please do not hesitate to open a new support ticket at WPML support forum.
