Table column headers of a new AWM app are not translated

1. Login with Admin and create a new app with AWM.
2. Check the column headers of the live table ("Page name", "Update date", "Last Author", "Actions" ).
3. Go to http://localhost:8080/xwiki/bin/admin/XWiki/XWikiPreferences?editor=globaladmin&section=Localization&space=XWiki and set :
*MULTILINGUAL > No
*SUPPORTED LANGUAGES > fr
*DEFAULT LANGUAGE > fr
4. Go back to your app homepage and check again the same headers.
5. Create a new entry in the app livetable (filling the fields you dragged and dropped).

Actual result:

• After action 4 > The column headers are still displayed in EN language, even if you did the FR language changes.
• After action 5 > The headers of the fields you dragged and dropped are also in EN instead of FR.

Expected result:

• I expect to see in both scenarios the translation in FR.
