If you view the Service Contacts for a case, but are met with a blank page, or no parties listed for the case, this indicates the Party Information is not being pulled from the court's records (Case Management System).
To resolve, you can start a test filing into the case. This will check the court's records for the Party Information. You can then go to the Service Contacts section from within a draft in the case, or view the Service Contacts from your Filing History, to be able to see the parties load properly.
