Background of the issue:
I have updated the text in the page of the primary language. To translate this page I opened the translation editor, but then the original text is shown. Not my updates.
Symptoms:
The primary language in the translation editor is not updated if I had made changes in the original text.
Questions:
Why is the translation editor showing the original text instead of my updates?
How can I ensure that the translation editor reflects the changes made in the primary language?
