I use for a document type a drop-down list with these options:
heimdienst;{$=Heimdienst|en-us=Home service$}
langzeiteinsatz;{$=Langzeiteinsatz|en-us=Long-term use$}
staplerfahrer;{$=Staplerfahrer|en-us=Forklift driver$}

On the livesite the options are in German:


Is that a bug in the cmsdesk? What I have to do that the options in the cmsdesk are in German, too?
