How to delete a broken cluster / project?

Hey guys,

my rancher is full of error logs. It tries to connect to an old broken cluster which I already removed. The web ui does not show me the cluster, but the rancher cli does. How can I delete such a cluster?

If I try to switch the context of the rancher cli to one of the broken projects (number 1 and 2) I can’t execute any other command.
