The widget description says:
This is your second home widget box. To edit please go to Appearance > Widgets and choose 7th widget from the top in area seven called Home Widget 2. Title is also manageable from widgets as well.
Unfortunately there is no such option to edit anything regarding those widgets. It seems like I can only edit the file 'sidebar-home.php' manually.
I can see the widgets, but on the right side of the screen outside any boxes.
