The settings configured in the Default Session either by navigating to Options > Edit Default Session or Options > Global Options > Default Session only impact new or ad-hoc sessions. These changes do not impact the settings for individual saved sessions that already exist.

You will need to modify the settings for the existing sessions using Session Options. If you would like to make the change to multiple sessions at once you can use standard Shift/CTRL-click behavior to select multiple sessions in the session manager then right click and choose Properties. You should see a warning confirming the number of sessions you are editing. Inside the Session Options choose Log File and make the needed changes.

Does this help get you the behavior you're looking for?
