Scrolling credits issue, image half invisible

I cannot figure out this issue or find a fix to it online. I’m trying to make scrolling credits with an image in a widget. The animation in the widget plays and the credits scroll up, but when they do…the image doesn’t show when what was out of frame originally comes in. If I have no animation and drag the image up with my mouse, it shows correctly but as soon as I add the animation, whatever part of the image is off screen does not show up when it scrolls up. Anybody know how to fix this?
