Conda environment not found and path issue

Hi, I am new starting out using virtual env for my projects. I recently installed Anaconda Navigator and learning how to make env using the terminal. But I have an env that cannot be found and the path doesn’t seem to be correct.

Using my terminal
(base) francesho@Frances-MAC ~ % conda env list

conda environments:

                     /Applications/anaconda3

base * /Users/francesho/opt/anaconda3
selenium /Users/francesho/opt/anaconda3/envs/selenium

I have one that is blank and cannot choose.

I have a conda extension on my jupyter notebook, and when I use this, I get an error message.
EnvironmentLocationNotFound: Not a conda environment: /Users/francesho/opt/anaconda3/envs/anaconda3

Here is screenshot of what’s under my conda

Questions

  • why are there two anaconda3 env
  • why am I getting an error message saying the path is not found. How to fix this? is it looking at /Applications/anaconda3 instead?
  • why is on the terminal I have /Applications/anaconda3, but I cannot switch to it. Is this normal?

Thank you for your help
