Hi there,
It doesnt seem like the slave filters work in the group editor:
Hey Laszlo,
I did a quick test and I was able to reproduce this. I will pass this to the devs to have them figure out why it’s not working.

FYI, looks like a patch has been put in and is up for review. I’m expecting it to land in SP13 but if not chase me on it.
