Try It Mode Text Entry Issues

I'm creating a software simulation using the step-by-step Try it mode. Every slide that has text entry requirement is simply a large white text box that covers the entire screen. For example, on slide 4 the hotspot is to click on the account number field. Slide 5 should be a spot where they type in the phone number, but instead it is simply a large white textbox. When I resize the text box to fit in the phone number field, I can't resize the text, so it looks terrible. Help!?!
