iStopMotion 3 shows zoomed in picture when editing or playback

Since getting the latest version when I am editing my stop motion animation the editing screen or playback screen shows a zoomed in version not the complete picture. How do I make it so it shows the full picture?

I have tried changing the overlay and aspect ratio but this doesn’t do anything about what is being shown. The overlay just changes the screen size while still showing the zoomed in image. The aspect ration didn’t change anything.

If there is nothing that can be done, how can I go back to a previous version which I know shows the full picture?

Any help on this would be greatly appreciated.
