Adobe Acrobat Prepare A Form Auto Text

[stacie357344320p41]

I have put autofill text in many documents, so I know how to di it, but with this new one I am working on, it is not making the text fill the entire text box. I have the font size set at "auto" but it isn't making it as big as the text box.  I also know that there is nothing wrong with the font because it is happening with any font I choose. My adobe does not have any current updates.
