I have the same problem in a NFL Super bowls library that is “TV Shows”, i was able to change that one to a “Movies” library and now renames behave as expected. but i can’t change this “TV Shows” library because of the rest of the content.
sure thing, here is the XML for “Opening Ceremony” ,after i’ve renamed it a 3rd time, while experimenting, i’ll add a new episode and get it to lose the info in a sec and post that xml as well. i don’t know what to sanitize and what to not, so i’m guessing.
i just noticed that the new episode i added, doesn’t have a title if that helps at all.
that’s prior to me making any changes at all.
it’s xml is here: https://pastebin.com/KF6D5Lcb
Since there is no such show as the olympic you need to set it as personal media. It is currently unmatched. At the show level, hit “Match”, then in the search box click on “Auto Match”, then select “Personal Media”. Now PMS will not try to match and will not change your names.
