Close Doors

When running through the checklists and auto FO selected ON, I get a Close Doors caption on the FMC. This does not cancel when the doors are closed. I cannot access the rest of the checklist as it thinks I have not closed the doors. Workaround = Set aircraft to Taxi state in the FMC.
I have found a workaround after a lot of testing. I played around with the aircraft states via the secret MCDU. I noticed that whenever i loaded up the "Taxi State" and then returned to C&D, the closed doors will be recognised and my flight crew will inform me that all passengers are on board. So I saved my default flight in "Taxi state" and also set the taxi state as default. Then I can select C&D. From there on everything is normal. I don't know if theres a problem
