Wallacei Parallel Coordinate Analysis

Hi,
I am using Wallacei 2.7 on Rhino 8 with 6 fitness objectives. In the Wallacei X component I can clearly see the most repeated solutions displayed as larger bubbles which is working correctly.
However in the Parallel Coordinate Analysis component (Method 0 - repeated fitness values), I cannot see the horizontal solution lines for repeated values.
I also checked the official Wallacei example file and compared with the YouTube tutorials, in the video the repeated fitness lines are clearly visible as horizontal lines across the parallel coordinate graph, but in my file and the example file I cannot see them.
Is there something I am missing in the setup to import maybe???, or is this a known bug in Wallacei 2.7 / Rhino 8?
Thank you

In addition to previous description of the Problem…These screenshots may help clarify the issue. The first image is from the training video, where repeated values are visible. However, when I open the same file in the Grasshopper/Rhino canvas, nothing appears in the graph. On the other hand, if I extract the output from the Parallel Coordinate Analysis solution, the values are shown as different data lines. It seems results are present, but they are not being displayed properly in the graph.

I tested the exact same script of example file in Rhino 7, and it works perfectly. The issue seems to be caused by Rhino 8’s new .NET architecture breaking the background solver. Is someone find a way how i can run into my Rhino 8 version…
