The door object has Floor Plan Dislay settings.
In the first image it looks like it is set to 'Projected' or 'Projected with Overhead'.
In the second image it looks like it is set to 'Symbolic' as it is showing a door swing arc.
The walls themselves also have Floor Plan Display settings, which may affect how the doors are shown as well.
I can't remember if the walls have any affect and I don't have Archicad running at the moment.
I always have my walls and doors/windows set as 'Symbolic'
