65.17 New Money Market Handling Feature - Not Finding MM Fund

I installed the 65.17 update on Windows and tried to customize the new feature that lets you specify a money market fund that should be treated as cash rather than as a separate position.

It's Merrill CMA account that has a low monthly transaction volume, so I wanted to customize it now rather than wait for the next download. Supposedly, your $1 per share valued positions should appear in the drop down, but none do for me, and there should be. Snips attached.

Is something set up wrong in the money market fund that is causing it not to seen? Or a bug?
