Cloud Backup settings inaccessible

My cloud Backup settings are inaccessible. I only recently added Norton Deluxe as my security. When I open My Norton settings page the only option for Cloud Backup is  Fix Now, there is no dropdown. If I click Fix Now it runs a backup with a default set which will be larger than the 50gb Cloud Backup allowed.                                     

How can I change the backup setting to set up a backup default set if Fix Now is only option?
