View button in entire slide without scrolling

Which template allows for no scrolling to view the next button?

I must scroll down to view the button when using specific image templates. However, some templates allow for a full-screen view without any scrolling. 

I've noticed that the button is visible without any scrolling. In the certified learning path videos, the instructors scroll down to view the unseen button at the bottom of the slide. Is this common? 

My client wants to display it so the learner will not have to do additional actions.  Any suggestions?

Thank you
