Unable to Load French Translations Drupal 8

Hi All,

I have set the default language to English and my second language is French. When i go to H5P editor in French site and select any content type the content type is still showing text strings in English.

I did not see any Console error or any other error. I can see in the console that the request was sent to the server like with session variable "?language=fr" But it is not loading the French files.
