Import Layer Issues

Whenever I try to import an image as a layer or a scene in Storyboard Pro, it moves to the bottom of the timeline and appears white in the camera view. The same thing happens when I open up a storyboard that already has imported images in it from a previous project. The drawings that are not imported are just fine and appear normally.

So, I want to know does anyone have an explanation and solution for what is causing this issue.

What’s your graphic card model?
How many monitors?
