prince: IndexingError: Too many indexers

Using example code:

import pandas as pd
import prince

df = pd.read_csv('ogm.csv')
mca = prince.MCA(df, n_components=-1)
mca.plot_rows(show_points=True, show_labels=False, color_by='Position Al A', ellipse_fill=True)

Error:

pandas.core.indexing.IndexingError: Too many indexers

I tried to find some details about how to fix myself to no avail. Many thanks in advance for your help.
