The translations of the ToolBox page are seriously out of date, and I don't think we can get them back in sync with the English page - it was at one time removed from the translation system and then reinstated much later, so now it thinks, that the existing translations are OK even though they are not.
Anne and I agreed that it is best simply to delete the existing translations. We'll wait a bit though, to give you time to rescue your work. Some of it can be reused.
From the page history it seems that your translation is quite recent, but still as far as I can see a translation of a fairly old version. Maybe the old translation units has been kept even after the English page was removed from translation?
