How can I update export setting? (per ExtrasReadme)

I am sure this is something simple and obvious to all, except me.

I was attempting to follow the instructions in ExtrasReadme.rtf but I wasn’t able to do the following:

Export Settings
• In Scrivener, go to File > Export Draft…
• Click on “Load”.

Export Draft is not clickable. What am I doing wrong?

Thanks!
