We don't know how this happens, but you need to delete one (either one) of the duplicates.
If you have any idea about how this might have occurred in your case, let us know.
Thanks so much, Mark!
There were duplicate entries for mhonarc, mail-archive, prototype, and hyperkitty. I removed them all and it worked again.
I asked the person who was making changes at the time what was done and she indicated that she had approved an email being held (from a non-list member) and then added a user to the list. Not sure which of those created the issue.
Thanks again!
