Electromagnet: No results (Time Domain)

I have trouble running the time domain tutorial of electromagnet.pro:

• All results are zero.
• The I(t) plot does not look as expected.

Steps

• ONELAB bundle from 13/05/2022
• Latest tutorials commit (070d2b1e)
• In Gmsh GUI, open electromagnet.pro
• GetDP/Resolution = Magnetodynamics2D_av
• GetDP/Post-processing = dyn
• Model parameters/Analysis Type = Time-domain
• press Run

Result

• Post-processing/j == 0, az == 0, and b == 0
• Plotting Model parameters/Current vs. GetDP/Time does not show the anticipated step-function (see code below), but a linear ramp from 1e-4 to 0.19

electromagnet.pro, line 67 ff.

    TimeInit = 0; // start simulation at time = 0s
    TimeFinal = 20e-3; // stop simulation at time = 20 ms
    DeltaTime = 1e-3; // use time steps equal to 1 ms
    // Define the time modulation of the current source, i.e. a linear ramp from
    // 0 to 1 until 10 ms, then a constant value of 1:
    myModulation[] = ($Time < TimeFinal / 2) ? (2 / TimeFinal * $Time) : 1;
