If you could enhance the error message below to include the Title of the Movie/Show impacted then it would make it easy to use the "Fix Mismatches" option to select a better option.
Seems like the few I have been able to figure out on my own have been flagged on their end as "Duplicates" and one removed so all I had to do is select the remaining one.
Error:
