filter not work on plan view

[wfrst2008]

Hi
I have filters in this file to control the visibility of a wall & a slab.
The problem is :
I can control their on/off in 3d view , but fail in plan view.
The slab seems not work.
I guess it's a view range problem, but my understanding is
filter should win in all situations.

Any help is much appreciated.

Not quite sure what's going on, but duplicate your floor plan view, and the filter works.:confused:
