Interpolation not working

For some reason I am not able to create an interpolation

Test.lml

Steps to reproduce

1. Open Attached project
2. Go to the interpolation curve
3. Recalculate

Expected

The interpolation curve goes through the data points.

Observed

The interpolation curve does not go through the data points:
