Slab thickness doesnt work on ArchiCAD 10 ?

[Anonymous]

Please help me how to change the slab thickness in ArchiCAD 10.
It always lock in 30cm thickness.
On my previous ArchiCAD 9, theres no problem to change in any thickness.

I use this design tool slab for making floors and also the canopy above the doors and windows. Stucked in 30cm thickness in flooring seems could be tolerated (although so bother n annoying ), but how to make 10cm thickness canopy for my doors n windows if this tool can not be changed ????

You have it set to a composite slab fill. Composites have their thicknesses assigned in the composite manager. Only simple slab fills can change their thickness.
