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.
