Can't turn off Plugins in Ultimate Branding plugin

I got the ULTIMATE BRANDING plugin so that I can hide plugins from clients. It's supposed to be done in the Custom Widgets area. The only four items I can check to be turned off are: Dashboard page and come back on this page.

 -Quick Draft Drafts
 -WordPress News

According to the Plugin info page (https://premium.wpmudev.org/project/ultimate-branding/#usage), here's a much longer list of widgets, including Plugins, I ought to be able to turn off. Can I turn Plugins off elsewhere now?
