My text field is scrolling sideways


I created a live text field for a note area for an interactive PDF. I converted my text box into a Text Field and selected it to be "Multiline" and "Scrollable". When I export my PDF, open it in Acrobat and start typing in, the text begins typing in the center of the box and scrolls horizontally all the way until it is out of frame.
What did I miss?
