I have a problem with Random Instance Rotation, when using Arc / Trim Curves node. I'm trying to do something similar in this tutorial, but only with Geometry Nodes.

Which results in this:
Arcs have different heights, which I want. But I can't make them rotate randomly on individual Z axis at all. The Random Rotation group does not work and I can't figure out why.

I have tried different combinations of the above and I am stuck. Is there a specific step that I am missing? Any help would be much appreciated.
Here is Blend file:
