Scrollrect Clamp Not Working

Hi All, I'm trying to implement a vertical scrollrect using the clamped movement type but for some reason it will not move when the type is set to clamp. If I set it to unrestricted or elastic it works but I need to clamp the contents to the view to prevent it from infinitely scrolling or snapping back to the middle. I have tried to disable the inertia and change with the options, but clamp just does not work. My Unity Version is 2020.3.11f1.
