Trajectories invisible in BFDA plot

[christianparet]

Hi,
I simulated a between-subject design and plotted the sequential BFDA illustration using code below. The image I receive looks like this:

Apparently, the trajectories are not shown.
I am new to R (used 3.6.3 version), so I might miss some trivial tweak to show/hide graph features.
Your help is much appreciated!

Code:
sim.H1 <- BFDA.sim(expected.ES=0.75, type="t.between",
prior=list("Cauchy",list(prior.location=0, prior.scale=sqrt(2)/2)),
n.min=20, n.max=300, alternative="greater", boundary=Inf, B=10000,
verbose=TRUE, cores=6, stepsize = 10)

plot(sim.H1, n.min=20, n.max=n_q80, boundary=c(1/10, 10), n.trajectories = 60)

Note: I posted a figure received from a different plot execution (below). Results look similar with both arguments in terms that the trajectories are not visible, and also don't come up with plot(sim.H1).

plot(sim.H1, n.min=20, n.max=n_q80, boundary=c(1/3, 3), n.trajectories = 60)
