How to reproduce

I am using Orca portable v2.3.0.
Flow Calibration generates 10 test objects with the same flow and a normal rectilinear infill pattern instead of the archimedean chords.

They are all identical.
I found out, when I took of the finished parts, as they have no difference.

Click on "Calibration"
Choose Flow rate and there ANY option. In this example YOLO

See the screenshot:
Orca YOLO Flow Calibration, rectilinear top most fill pattern, no "Advanced" section at the "Quality tab"
and there is no "Flow ratio" or anything similar.

Also there is no change visible at the Object settings summery:

Actual results

Maybe I am just looking at the wrong places but it appears that the Flow Calibration is not working at all - and the printed result tells me that the flow is indeed not different between the objects.

Expected results

Calibration parts should differ in the flow ratio.
