Auto filter on a group channel in Ableton

I’ve grouped my drums into a single Group as usual. This time I’ve put a standard Abelton auto filter on the Group channel and tried to filter the drums. It doesn’t seem to be actually working much if at all.

I’m at a loss why? Any ideas? Each drum track is routed to the Group Channel.

Ha ha. Just figured it out. I’m stupid sometimes.

I’ve just started to use Returns for some drum and synth channels processing. So I can keep a dry signal unprocessed. Anyway, so of course, the remaining unfiltered sounds I was hearing were coming from the returns. All I had to do was copy the filter plug and it’s automation to the Return channel and it all worked.
