KevHal​ This should no longer be an issue at this point. If you are still experiencing issue please restart the device and run the following task:

Start-ScheduledTask -TaskName "\Microsoft\Windows\PI\Secure-Boot-Update"

Note: The task runs automatically every 12 hours so this should work even if you don't run it manually.
If you are still experiencing issues today, please raise a support ticket.
