ATE not behaving as in documentation

After installing pyATE as for documentation, if I run the examples in the documentation I get different and worst results.

Running:

from pyate import combo_basic

string = """Central to the development of cancer are genetic changes that endow these “cancer cells” with many of the
hallmarks of cancer, such as self-sufficient growth and resistance to anti-growth and pro-death signals. However, while the
genetic changes that occur within cancer cells themselves, such as activated oncogenes or dysfunctional tumor suppressors,
are responsible for many aspects of cancer development, they are not sufficient. Tumor promotion and progression are
dependent on ancillary processes provided by cells of the tumor environment but that are not necessarily cancerous
themselves. Inflammation has long been associated with the development of cancer. This review will discuss the reflexive
relationship between cancer and inflammation with particular focus on how considering the role of inflammation in physiologic
processes such as the maintenance of tissue homeostasis and repair may provide a logical framework for understanding the U
connection between the inflammatory response and cancer."""

print(combo_basic(string).sort_values(ascending=False))

I obtain:

Does the package need a special config to be set?

I think it could have something to do with the fact that spaCy's process is stochastic or the fact that I ran this on a previous version of spaCy, although I'm not too sure.
