Automation Email Server Settings

When initially setting up the Emal Server Settings, I input the wrong Login ID and Password. When I try to schedule an automation script using Email as one of the tasks, it retrieves these incorrect credentials and the task fails. I can manually change the credentials and the script runs fine, but if I reopen the script, the incorrect ID and Password are still there. How can I permanently remove the incorrect credentials?

Thank you in advance.

I suggest opening the automation script in notepad and editing manually. You can see the xml values.
