I think this breaks the rules of IRV, which asks for several different
options.

I think this breaks the rules of IRV, too. If in both cases, the votes were
required to provide 5 different options, it would have changed the
distribution of votes. And there's quite a number of other duplicate
selections.

However, the only fix would be to ask the original votes to recast the
votes. Simply removing duplicates from each preference vector does not
change the results.
