I believe it has more to to do with the word “Ending” and not the word “Alternate.” It also affects alternate opening scenes.
I posted here, Local Extras Display Name Problem and if you can make sense of the way I was told to name them, even though there’s no documentation or reason as to why it was changed, let us know. I ended up using different names for the extras, like “Alternate Final Scene” or “Alternate Beginning Scene”
