ValueError: keyword grid_b is not recognized

In a Windows / python 3.9.2 environment the following error occurred:

Fixed by changing "C:...\Python39\site-packages\SLiCAP\SLiCAPplots\SLiCAPplots.py" lines 370-371 from:

fig.axes[i].grid(b=True, which='major', color='0.5',linestyle='-')
fig.axes[i].grid(b=True, which='minor', color='0.5',linestyle=':')

to:

fig.axes[i].grid(which='major', color='0.5', linestyle='-')
fig.axes[i].grid(which='minor', color='0.5', linestyle=':')

Was my installation wrong or was I perhaps missing something or did someone encounter this error before? matplotlib.axes.Axes.grid does not show the parameter/keyword 'b':
