Hello Clinton and James!

Welcome to our Forum, it's nice to have you with us. Thank you for finding time to report about the issue, I will be glad to help you with it.

It looks like the Scheduler glitch, and we can try the following steps to resolve the issue: 

1. Update Scheduler as mentioned in this article
   If it doesn't help, please:
2. Download Acronis Scheduler Manager. Open command prompt (Start -> Run -> cmd); run schedmgr.exe and issue the following command:
   task zap
   This will erase all traces of the tasks.
3. Reboot the machine
4. Recreate the tasks

Please note that task zap command will delete all the tasks. In case you need to remove just one task, please follow the below instructions: 

1. Run schedmgr.exe and issue this command
   get list
   It will provide you with the list of tasks you have
2. Find the one you need to delete and enter the following command:
   task [task_number]
   This will get you to this task menu
3. As soon as you are in the task menu, enter
   Delete
   and the task will be removed

This should resolve the issue faced. Should it persist, please provide us with Acronis Info.

Should you need anything else or have any further questions - feel free to contact us at your earliest convenience, we will be happy to help you!

Thank you!

This seems to have solved this issue. Thanks.
