My guess is since this is a post rendering option the way it is intepreting what is a vector for this effect needs to be adjusted.The replicator is new so my guess is this unforseen consequence just got missed. I have also seen something with combining modifiers/particles in the same scene cancel out effects, but don't know if that is a bug or design limitation...will have to check and possibly report it.

No need to think outside the box....
