Gap in spline/spline mesh component at start

Hey

I’m having trouble with spline mesh components, Can anyone explain why this node system doesn’t work? Is there something I’m missing?

It always leaves a 539uu gap before the first mesh begins.

Update:
OK so I’ve printed the location of the location that feeds spline point 0, spline point 0 and the first position of the first mesh, and they all match.

Visually there is a sizeable gap still

Update

Turns out I had something called a degenerate derivative problem

Because I was manually setting tangents at spline points with 0s to create no tangent. It was causing a massive issue Lol. Learn a bit more every day. It’s not solved But at least I’m closer.
