WPML Media translate error

I have a problem with the title and description of the images on the translated pages.
The plugin works fine in the default language, but does not work with translated images (same image, different title and description).
Use wpml media for machine translation. http://wpml.org/documentation/getting-started-guide/media-translation/

Do you know how to solve it?

thank you!
