exercism configure not saving configuration

Hello,

I'm trying to get my token set up so I can download exercises. When I run the command to configure my token I get the response:

> You have configured the Exercism command-line client:
>
> Config dir: /home/brian/.config/exercism
> Token: (-t, --token) 7b1e2471-c246-4aee-a288-53ff07ac9fbe
> Workspace: (-w, --workspace) /home/brian/exercism
> API Base URL: (-a, --api) https://api.exercism.io/v1

However when I attempt to use exercism I get the prompt to configure again. Checking exercism troubleshoot I find:

It seems that I still only have the default configuration in place. I've rebooted a few times to make sure I don't have some strange state from installing. Is there some configuration file I can just manually edit?

Cheers
