qtranxf_translate_object_property doesn't work propertly

[valentynilinov]

qtranxf_translate_object_property() in qtranxf_translate_post() translates good
and wp_cache_add() caching translated versions for post_content, post_excerpt, post_title
so the cache has post_content, post_excerpt, post_title and post_content_ml, post_excerpt_ml, post_title_ml

and doesn't get both versions for the /wp-admin/post.php?post=*&action=edit page
and doesn't get both versions for the_title, the_content, the_excerpt filters.

Could you help or fix it, please
