I'm a little confused about the "reply-to" setting as I was pretty sure I had set my list up so that all replies by default go back to the list, but for some reason a reply goes directly to the sender.
If you set "reply_goes_to_list" to "this list", "reply_to_address" is ignored, and Mailman adds the list posting address to a Reply-To: header in the outgoing mail. If there is an incoming Reply-To: and "first_strip_reply_to" is "no" the address is added to the incoming Reply-To:. If there is no incoming Reply-To: or "first_strip_reply_to" is "yes", the address is the only address in the outgoing Reply-To:.
If "reply_goes_to_list" is "explicit address" then "reply_to_address" is added rather than the list posting address. If "reply_to_address" is the list posting address, then it's the same as "this list".
What actually happens with "reply" depends on a few things. If the mail client involved is Thunderbird, it doesn't behave as expected. See https://bugzilla.mozilla.org/show_bug.cgi?id=1309486. In short, in recent T'bird if the message has a List-Post: header and T'bird offers a "Reply List" button, "Reply" will ignore Reply-To: if it's the list address and reply to the From:. In more recent T'bird, you can restore the expected behavior be setting mail.override_list_reply_to False in the config editor (see https://bugzilla.mozilla.org/show_bug.cgi?id=1392371), but this has to be done by every list member that uses T'bird.
There are other possibilities, but I think the above is the likely issue in your case.
