Thank you for your reply
I managed to fix the problem just now. The solution was not the settings in office, nor was it the display language in Windows. It was the input method. This was set to English. When I changed the input method to Dutch the proofing language nog longer defaults back to English in Word.
To change the input method press windows key + space (keyboard layout shortcut)
