We just started a new Jira Service Management project, and although I'm not the space owner, I'm an admin of the project with ALL user roles and I'm also a Jira admin. I still cannot edit many of the settings pages like any of the Request types (e.g. Service requests, incidents) nor Channels & self service (e.g. Portal, E-mail). Each page just shows a "This space isn't available" - "It may have been deleted or your permissions may have changed" error with no explanation otherwise.
Any assistance would be appreciated -- we're evaluating this product vs. other services and Jira won't even let us configure the project whatsoever -- not a good start.
