FO1 Not Displayed in Parallel Coordinates Although Values Exist

[Mana]

Hi,
I am using Wallacei for a three-objective optimization (FO1, FO2, FO3).
FO2 and FO3 are displayed correctly in the Parallel Coordinate Plot, but FO1 does not appear at all—there are no lines shown on the FO1 axis.

However, when I connect a Panel to the FO1 output, the numerical values are clearly visible, so the simulation itself seems to be running correctly.
The geometry also updates properly when the genes change.

My question:
What could cause FO1 to be omitted from the Parallel Coordinate Plot, even though it outputs valid numerical values?

Thank you.

The value of FO1 is not changing while simulation is running. We have responded to this issue multiple times in the forum.
