negative probabilities when running bump in the night

I have been trying to reproduce the analysis bump in the night and the code is returning an error

Steps to reproduce:

1. Git clone and pip install in standard igwn environment.
2. mkdir /home/ovgu.guleryuz/mockcatt
3. mkdir /home/ovgu.guleryuz/mockcatt/out2
4. mkdir /home/ovgu.guleryuz/mockcatt/sensitivity
5. copy and modify the bump_inthe_night.ini file

(igwn) [ovgu.guleryuz@ldas-pcdev11 mockcatt]$ diff -u ../mock-PE/bump_inthe_night.ini bump_inthe_night.ini

6. Run the following
