This is how to work with widgets.
1. From the Widgets Screen, Click ‘add’ to add a widget.
2. Then click ‘save changes’ on the right side of the widgets screen.
3. If you want to delete, you click the ‘Save Changes’ a second time.
Note: When you delete, all widgets will be deleted, just go back and ‘Add’ the widgets and ‘Save Changes’ for the ones you want back!!!
Hope this helps.
