Spline Mesh Complex Collision

I’ve seen posts about this not working in packaged games but I can’t even get it working correctly in editor.

I have a spline mesh tube and I want it to have collision along its length. I’m trying to use complex collision as simple here cause it need to collide from the inside.

But whenever I compile the blueprint the collision just sticks on the end like this (i think it’s all the collision meshes stacked on top of each other). I tried checking “Allow CPU access” in the mesh settings and it didn’t do anything.

Here is the blueprint and settings

It seems like only the preview of the collision is bugged. The collision responses actually function correctly at runtime.
