Sorry, I thought those were only for the language I was translating, I didn't know they shold not be translated. Maybe there slould be a message informing the users not to translate them, or is there already one and I didn't notice? Sorry if so! :)
It already said that. In the translation interface on the left it says "Your translation" in the language you choose to translate to, which can be changed in the upper right corner in Special:Translate.
On the right, above the suggestions, it says "Edit documentation". Of course this strings are translated to the language you choose for the GUI and can be changed in Special:Preferences.
