Export Scheme Edit not Persistent

Having an issue with my Autocad Export Scheme not being persistent on save.

Ive saved the updated scheme from within my drawing template (startup) but everytime I open a new DWG file and then go to save i have the old scheme showing.

Any help with this would be greatly appreciated.

Seems that its no longer possible for me to save changes to the DWG export scheme that loaded with Rhino. Created a new pref file with the settings I need and that file it is now persistent. I’m guessing a file permissions issue?
