Leaf Option translation problem on Admin page

If you use a child theme, the languages files have still to be in the main theme.

( because in theme-functions.php the “load_theme_textdomain” use “get_template_directory” and not “get_stylesheet_directory” … )

I put the language files in the main theme and child theme

theme-functions.php
/**
* Make Leaf available for translation.
* Translations can be added to the /languages/ directory.
* If you’re building a theme based on Leaf, use a find and replace
* to change ‘leaf’ to the name of your theme in all the template files.
