I see what you mean -  I don't think it's you. I've filed a bug in our internal system.. thank you for bringing this to our attention. Interestingly it does work for the Full Copy and the Preparer Copy.

Also that's a brilliant way to show me how painful it is to move something in that dialog from the very bottom to the very top.  I'll look into adding "move to top" / "move to bottom" buttons 🙂
