E61 door showing as open when closed??

[Tompug206]

Hi guys went to view an e61 530d tonight and was a lovely car however I noticed the drivers side door is showing as open on the display when it isn't.

Had a look for a switch on the door frame/door and couldn't see one. It did put me off the car as it meant the car couldn't lock.

Love the car so hoping it's a quick fix.

Any ideas?
