Unable to change NonStop Backup settings

I upgraded from True Image 2014 (Build 6673?) to True Image 2015 (Build 6525) yesterday.

True Image 2015 imported my existing NonStop Backup and Disk Backup settings but I cannot find any way to access and change the NonStop Backup settings via the UI.

If I right-click on the Disk Backup task (in the "My Backups" panel) I see a menu with "Edit settings", "Validate", "Open location", "Clone settings", "Move...", "Remove from the list" and "Delete".

But if I right-click the NonStop Backup task (in the "My Backups" panel) the menu offers "Remove from the list" and "Delete". There seems to be no way to add or remove files/folders to the NonStop Backup task.
