I started a thread about this as well, no one replied, it is on the next page or so. I do not see an option on the FMC to close baggage doors - would be easier if so. What I have to do is, after the luggage loads, I have to use the FMC to call PMDG's loaders then recall them after the connect. When PMDG's loaders depart, the doors close, so it is probably a PMDG issue - maybe.
