Cut plain disappears Archicad 20 Mac

[Anonymous]

When I place a 'section cut' I see the purple line in my section. When I open my 3D model, there is no 'section cut' at all. It also disappears in my section. What do I wrong?

I try to do the tutorial 'Adding a Terrace Slab - ArchiCAD 18 Training Series 3 – 13/52' on Youtube. The step of the 'section cut' is on 01:50min.
