New Project: Unable to Change Initial Settings

Using Unreal 4.13.2 on Windows 10, when I load up and select New Project > Blank, I am unable to alter the additional settings below: Desktop / Console (choose the overall class of hardware to target - desktop/console or mobile/tablet), Maximum Quality (choose graphic level), and With Starter Content (enable to include starter content).

Mostly, I’m just wanting to start a project without the Starter Content, but nothing happens when I click on any of these buttons. I can go ahead and Create Project and get in to Unreal and use the program, but I’d ideally like to start a truly blank project.

Can anyone point me in the right direction, or advise why I might not be able to adjust these functions?

Appreciate it!
