Projects are being squeezed after loading up making it impossible to work

My videos are being 'squeezed' on the sides whenever they are loaded into Rush. If I open an old project, the same. If I open up a new project and load a video it will initially look fine until it is fully loaded in (the status circle in the top right starts indicating that it is loading it in) once it's finished the video is squished. They will export fine, but this makes it nearly impossible to make videos and is very frustrating. I've reinstalled the program, logged in and out of CC, all the things.
