Difference in scene view and camera preview

I have 2 assets on the scene. I positioned them to get the camera view correct, but the scene view is different; the background is stretched out past where it should be. I should also mention I needed to scale the background 2x to get it to look the way I wanted it to in the camera preview. Am I doing something wrong during the asset import?

Here are the representative images:


In case anyone else is having this issue, changing the Main Camera from Perspective to Orthographic solves the issue.
