Spline Mesh collision issue causes physic object (ball) to bounce

Hey all, I have a simple project set up. The basic premise is this; a series of balls roll down a track mesh that is generated by a spline. It sounds pretty straight forward. The issue that I’m running in to is that at some points along the spine mesh where one mesh ends and another begins, the balls will bounce for no apparent reason. I am using the “use complex collision as simple” setting on my base mesh. The video below depicts my issue.

I have tried applying a more simple (less curvy) custom collision mesh but the issue still persists. Even when I build the mesh track in 3ds max, split the mesh in to segments, and then import into unreal, whenever I apply complex collisions the jumping always occurs where one mesh ends and another begins. Any help would be great!
