conda not deactivating properly

[paulray]

There is some problem deactivating the fermi conda environment. After deactivating, I still have that python on my path. See:

% which python
/usr/bin/python

% conda activate fermi-2.2.0

(fermi-2.2.0) % which python
/Software/miniconda3/envs/fermi-2.2.0/bin/python

(fermi-2.2.0) % conda deactivate

% which python
/Software/miniconda3/envs/fermi-2.2.0/bin/python

But for my other conda environments, it works fine.

% conda activate hese

(hese) paulr@hesenode1:~ % which python
/Software/miniconda3/envs/hese/bin/python

(hese) paulr@hesenode1:~ % conda deactivate

paulr@hesenode1:~ % which python
/usr/bin/python

Is there something about the fermi tools that is making this not work?
