A big bug in FORTE tool (sector generator)

  I was using ANSYS FORTE for IC engine simulation and found a serious bug when creating a model using SECTOR GENERATOR.
  After setting the engine parameters and clicking APPLY, in the image on the right side, you can see that the planar shapes are not in one plane (head and liner are in one plane, but the piston bowl is in another plane), and therefore the mesh cannot be meshed in the next step.
  At first I thought it was a version issue, so I tried several versions 2019-2024, again with the student version, and realized it wasn't a version issue. I then focused on my own computer and thought it might be a computer problem, so I went to the school's teaching team's computer to create the model, but still had the same problem.
  So I would like to ask, how do I fix a problem like this.

  Hi:
  The appearance of the profiles is normal. I ran a test here, and my mesh looked the same, but meshed up well. The issue is most likely with the placement of the control points, or the fact that you are generating a 360 mesh, which is NOT a sector
  Here are my settings:
  and the resulting mesh:
