Why is the camera blocking volume not blocking my camera.

I’m making a 2d platformer and the camera in question is stored in the character BP on a spring arm, but, whenever I add a camera blocking volume into my level, the camera just jitters a bit and then clips through it anyway, as if the blocking isn’t working within the box. I’ve tried everything from setting the cameras world/relative location each tick and clamping it, neither of these worked.

Check this out, it could help.
