You've found our new code Console, which is still a work in progress. There will be more to share on this in the coming weeks, but it's not yet live. Until we are up and running with our new code Console, we're recommending using our live version: https://code.cerner.com/developer/smart-on-fhir/apps
For the issue you've reported - we're taking a look into what's happening. Can you confirm if this was a system application you were registering? If so, can you share the System Account you're using?
