There is another actress named Peyton List. It refers to union actors (SAG, AFTRA, AEA). Once a name has been registered with the union, it cannot be used by someone else. The reason is simply that you could not be distinguished from the other actor of your same name without a description or picture every time. If you are non union actor you can keep your name.
I read that the first Peyton List registered with SAG-AFTRA with her middle name. That's why this Peyton List was able to register her name without her middle name or middle initial. Since the first actress has never used her middle name on screen credits, we have the confusion that we have today.

Now that I know that, I am curious what the other Peyton List's middle name is.
Peyton Elizabeth List.
