can't extract the date from following string

matches = list(datefinder.find_dates(s))
print(matches)

#it returns empty list

It seems that datefinder can not extract the date if there is a digit following it:

>>> list(datefinder.find_dates("11/20/1972"))
[datetime.datetime(1972, 11, 20, 0, 0)]
>>> list(datefinder.find_dates("11/20/1972 4"))
[]
