Those projects are defined in a parent project. To edit them, open the parent project (probably called global). In 8.0.1 you’ll be able to open them in a read-only view.
In either case, you can also make local changes by right clicking them to ‘override’ - however, this is strictly a local-to-the-current-project override - you’re not editing the actual resource definition on the parent.
