Import image to stage becomes too small

Have this ever happened to you?

I imported an JPG image to stage. But when I look at the image on stage, it looks too small – much smaller than the image native size. Normally, it should import at the image’s native size.

So then I delete the image from stage and pull that same image from the library back onto the stage and then it is at the correct size.

What is causing the image imported to stage to become so small?
