Don’t know if it’s a Unity issue, since I’ve seen it in some other assets before, but sometimes when creating a new node, the title of the last node will already be inputted (but should not be), even though the title is actually the default “Action State”.
No problem! I noticed it occurs as well in an action list if there’s two actions with a dynamic variable, when you rename one variable, then click the eye to select the other action, the problem happens too.
