I can't help with the why headers are being removed for both. However my
thought is that you might want to be a bit careful with

"$h_from:" contains "abc@???"


as I'm pretty sure it will also match when $h_from is, say, "zabc@???"
(because this also *contains* "abc@???").

Mind, I might well be wrong as I've only used a system filter in one
situation, and that was about 10 years ago! :-)

Cheers,
