Eng Oil Servicing Door Open after servicing - how to close?

[AggieRotorhead]

In V1.8 I serviced oil for the first time after shutdown.  The next time I started I got an External Door Open alert and discovered that it was due to the oil servicing door being opened.  I can only surmise that although you can't physically open this door in the sim, something thinks it is open.  Screenshot attached.  Any idea how I can shut it?  It's also causing ground crew to give me a thumbs down prior to starting #2 I think.
