ValueError in FAST sampler, reading CSV ("X columns instead of Y")

I'm trying to run a small test (i.e., small number of samples) of FAST so as to become more familiar with how it is implemented here.

# cal_process is an instance of the class that has "evaluation" and "simulation" methods, etc.
fast = spotpy.algorithms.fast(cal_process, dbname = 'RECO', dbformat = 'csv')
with warnings.catch_warnings():
    warnings.simplefilter('ignore')
    fast.sample(10)

This same dataset and sampling scheme works perfectly well with ordinary MC (spotpy.algorithms.mc()).

However, FAST fails to produce any meaningful results due to an apparent issue with reading the CSV ("database")...
