You found a bug. The software is trying to create a step for every time point, but the name of each step is using a truncated time in the name. It ends up trying to create a step with the same name, and is unable to do so. It aborts the current step's creation and goes to the next step.
I'll file a PR to get this fixed. I'm curious why you need such granularity on the time steps though. I believe you stated previously that creating fields were giving you a similar problem? The data points from very close time points were being treated as duplicate.
