Can't create a develop preset in new version of Lightroom

After clicking the + symbol to add a new user develop preset, I get a dialog box that looks like a 'copy settings' box. Next I choose "none' to turn everything off. Then I click "create," expecting to do a series of develop commands like I did in earlier versions. But nothing happens. The dialog box closes and there is no new preset in the list.

Previously, after initiating a new preset, I would manually do all of the develop adjustments I wanted and THEN click "create."

I'm using LR classic 13.0.1

I tried multiple searches on the healp site, getting nothing relevant.
