How to change language in menu bar

[skyeliner]

Right after installing MC SE v15.5 Build 3103 the menu bar showed German titles in the menu bar (Datei, Einstellungen etc). After restart it now shows all in English (file, edit, configuration etc). I did not find a way to change back to the German language. Can somebody please help and advise what I need to do?
