French trranslation issues

I fully translated your plugin.

Something includes/translation/class-translation-text-search.php isn’t fetching the ‘fr’ strings

My language settings:
define(‘DOPBSP_CONFIG_TRANSLATION_LANGUAGES_TO_INSTALL’, ‘fr’); // Set the languages you want to install. Add the abbreviations separated by commas.
define(‘DOPBSP_CONFIG_TRANSLATION_DEFAULT_LANGUAGE’, ‘fr’); // Set default language.

How can I fix this, it’s pretty annoying for my users
Thanks
