Intentionally deceptive advertising of Nova Launcher Prime features is my the issue. It states about the Prime version:
"Custom Drawer Groups - Create new tabs or folders in the app drawer"
You can make folders in the settings, and they show up in the App Drawer, but you cannot drag apps into them, like you can with the stock TouchWiz launcher. You can only drag them to a home screen, and then drag apps into them. There is little need for folders on home screens. Home screens contain normally used apps. The App Drawer contains all of your apps.. Here Nova Launcher removes all of the apps from their stock TouchWiz folders, throws away the folders, and alphabetizes the apps, so you pick up pages and pages of apps in your app drawer. Now try to figure out which apps are whose. Gone is the organization that comes with the standard TouchWiz where you have the Google apps in the Google folder, the Samsung apps in the Samsung folder, the Amazon apps in the Amazon folder, the Tools in the tool folder, the wireless provider's apps from their folder, and any folders that you may have made to organize your apps. This deception is intentional. If you do a little searching, you will see they have been getting comments from angry users for a long time from people getting deceived on this point. It was for the most part the reason they paid for Prime. However, they would sell very little Prime if they were honest.
