No, you are not imagining things, and it is not a problem on your end.
It looks like Yahoo Groups has some hickups in the past few weeks.

BTW: the X-UIDL is mail server (or maybe even mail client) specific, but
you can trace the duplication/divergence in the 'Received:'-headers of
the mail.

One of the yahoo.com mail servers will send the message with two (or
three) different ESMPTS ids, which means it was asked to send the
message twice to your address. That would seem to indicate that the
problem is somewhere with the way Yahoo Groups sends out the emails to
its subscribers.

I'm not sure if we can do much about it. Yahoo (and now Oath) haven't
really done anything with Yahoo Groups in the past 10 years but only
kept it alive.
