OpenNest plugin. Overlapping geometry due to poor data structures

Hello, guys.

I am unable to solve this overlapping curvature geometry by myself. I ask for help

Instead of blabing, I am leaving a screenshot of the described problem and GH file with script.
I’d like to solve this by my own, but not sure how data trees works, and, in this case, it seems that the problem is due to uneven data structures that I am plugging into Text component input from OpenNest plugin.
