Error when running `storj-sim network --satellites 2 setup` on test net

When trying to spin up satellites on the test net using the storj-sim network --satellites 2 setup I get the following error - Unrecoverable error {"error": "CA certificate and/or key already exists, NOT overwriting!"

Can someone please explain what is happening and how to resolve this. I am running on Mac os. and referencing the test net tutorial here -

It could mean that you already ran storj-sim network setup before and didn’t delete the previous instances. You would need to run storj-sim network destroy to delete the previous instance. Alternatively you can use storj-sim --config-dir <somedir> network setup --satellites 2 to create the sim in a different folder.
