I have set a task to run on HyperBacckup to back up to Synology C2. I now realise that I wanted to encrypt the task so I set a separate task just how I wanted it and clicked cancel for the unwanted backup. The unwanted task is stuck on Cancelling and the wanted task says waiting. Logging into Synology C2 and trying to delete the backup returns the message operation failed. How do l clear the unwanted task that seem to be stuck ?
