Okay, I just did some experiments using [Child Actors] and all of mine will allow me to change [Defaults] in the [Details] panel. I don’t know why yours isn’t showing up. When I click on my [Child Actor] in the menu on the left-hand side, a menu will appear right under [Child Actor Component] (called, [Child Actor Template]) where I can set all of the class [Defaults], including all of the variables attached that will change its appearance, such as text.
