Door Casing not showing in Section

[Anonymous]

Hi,

I'm am trying to activate my door casings to show in section but they don't seem to want to show up. They are showing in 3D & in the settings dialog, but I can only get the width of the frame to show in section and not the casing itself.
I thought it may have to do with my frame thickness being set to 0 but I changed this to 20 and it doesn't seem to have helped. I also can't see any Model View Options that would control the casing. Any help would be greatly appreciated.

Section screenshot. I have also played with the scale sensitivity settings without luck.

If you start a new project with New & Reset and place a Door with default setting, does the casing then appear in Section?
If yes, then there must be some setting for that Door in this file.
I tried this on a newly created file and the casing is there for me in Section too.
