Are some lists in Non-digest options -> regular_exclude_lists of other
lists? If so, e.g. if list2 is in list1's regular_exclude_lists, you
won't ever receive a copy from list1 since you are a member of list2.

However, it doesn't sound like this is the case because if it were, the
order of message approval wouldn't matter.

It seems much more likely that Mailman is sending a copy from each list
and some MTA or MDA between Mailman and you or your own MUA is
discarding all the subsequent copies after the first because they have
the same Message-ID as the first.

You are correct that that does not apply in this situation. The only
Mailman thing that might apply is regular_exclude_lists.
