Revit Generative Design gives only 1/4 results

Hello
I’m studying Revit(2024) generative design.

When explore outcomes there are only 1/4 results with geometry and other results have no geometry and results.
If I choose to make 40 results , only 10 results have geometry.
If I choose to make 60 results , only 15 results have geometry.

Why this happens? Please someone help me with this.

I tested Autodesk Samples-Three Box Massing, and it works fine…
Maybe my dynamo script is problem…
But If there is anyone knows how to fix it, please give me the answer…

A possibility. Can you post your dataset and graph?
