If the pre-comps have collapse transformations enabled then any effects
applied to them will eliminate 3D intersections.  Is the problematic layer
a continuously rasterized vector file?

I think your best bet is to circumvent applying the Expression Controls to
the pre-comps and instead apply them to a Null.
