Automation designer is not saving the latest progress

Hi all,
I've got some issues in automation designer:

  1. Toad automatically saves/rewrites backup to certain timing but not to the latest.
    The auto-save is probably not working properly. Seems there's no explicit save button for the tasks in automation designer, or do I just miss it?

  2. Not able to remove task in Toad Task scheduler
    I ended up deleting the task through PC Task Scheduler. But why I'm not able to do it anymore in Toad Task scheduler? If I remember correctly, it used to work.

The Toad version I have is 17.0.341.1977.
Thank you!

Irene
