[Resolved] translation of one post disappeared after editing post. can't add new translation

Problem:
You are experiencing an issue where after editing the formatting of a translated post, the translation disappears and cannot be added back. The translation saves in the advanced editor, but does not appear in the dashboard.
Solution:
We recommend the following steps:
1. Go to the top right corner of the translation editor.
2. Click the gear icon.
3. Enable the option "Use the previous version of the Advanced Translation Editor."
4. Refresh the page.
Next, follow these steps:
1. Navigate to your Dashboard > Pages.
2. Open the edit screen of the original page. Look for a pencil/circle/gear icon in the sidebar options under the "Languages" section.
3. Make a small change, such as adding an extra blank space at the end of a sentence or paragraph.
4. Save it. You should now see a circular arrow beside the second language's links, indicating that an update is required.
5. Edit the translation again and ensure it is saved up to 100% translated.
