UI (apache/skywalking-booster-ui)

What happened

In version 10.2.0, for a simple trace like "A calls B and C," the UI shows 5 nodes instead of the expected 3. The API correctly returns 3 spans, but it seems the frontend logic incorrectly attaches each segment group to the root, creating a broken tree.

What you expected to happen

I hope these detailed suggestions are helpful for locating and fixing the bug. I am willing to contribute or create a Pull Request if I can get some guidance from the team.

How to reproduce

The issue is reproducible in any scenario involving multiple segments.

Your description doesn't make any sense. spans don't mean the number of RPCs. I don't know how you got this feeling

We could check the 2nd view.
But your previous description is hard to understand.
