The deployment diagrams contain some greyed-out elements https://docs.opsmanager.mongodb.com/current/core/deployments/#highly-available-application-and-multiple-backup-databases.
For example, the HTTP service on server 3. It's not clear whether it means the service should be disabled (on Windows installations) or whether its simply inactive.
Also, it's unclear why the HEAD DB stencils are greyed-out.
Could that be fixed please?
