1.) 1.) Start the system and navigate to Control Panel → Configuration → System Settings → Web Content. Under System scope select Administration and enable ‘Changeable Default Language’.
2.) Start the system and navigate to Control Panel → Content → Web Content, here create the structure and the template that is attached to the ticket.
3.) Using the structure please create a new article. Change the default language to French and add data to all fields and publish it.
4.) Edit the article and use the language flag next to the summary and try to add a new translation.
Result: The data from the summary field is lost.

The effected fields are title and summary, the root cause is we do not consider the changeable defaultLocale feature and we take the defaultLocale from the ThemeDisplay in journal-portlet
