Can't remove folders in Shortcuts app

Using Shortucts for first time, there were default folders like Zoom and Amazon and others. They are under a heading "App Shortcuts". I can't delete them. they don't come up in the list when I hit 'edit'. I've restarted the phone and deleted the app and reinstalled. Interestingly the same folders came up again insoide the Shortcuts App.

Any help greatly appreciated.

Thanks
