Overlapping zones can be a problem and are best to avoid if you can.
Check the view settings of the schedule (in the view map and not the project map).
Here a layer combination is saved in the settings.
Is it the correct one that hides the layers of the zones you don't want.
You don't say what version of Archicad you are using but fortunately in version 20 you can simply edit the layer combination in the view settings.
In earlier versions you can't and will have to re-create the view with the correct layer combination again.
If that is not the solution then I think it is just a problem with overlapping zones and the objects can't determine which one they are associated to.
