Translating the locale_xx.js file


Im have created a locale_sv.js file for translation to to a swedish version. All works great but i have one word i cant translate its ‘Description’.
Se this screenshot.

Is it a bug or am i doing anything wrong?

Above screenshoot was taken from standalone scheduler of from plugin?

From WP plugin

In case of WP plugin - labels for section in the lightbox will be taken from “Custom fields” dialog in the admin part of scheduler - the simplest approach - set necessary label in the admin part.
