"Configuration parameter token specified is invalid" when trying to set DB Parameter AUTO_REVAL. (4231852)

When working in a database details window | DB Parameters tab, the AUTO_REVAL "Deferred" setting cannot be set.

Click on the drop down for that setting and select one of the options (i.e. DISABLED).

Click on the check icon to "Save Change".

This gives a message nothing the script for this change. Click OK to that, expecting it to run. But instead it gives an an error message.

The parameter is not updated for the database. If the same script generated is manually run in command prompt, the parameter is correctly changed in the system. After manaully making this change, it is still not reflected in Toad.
