Hi @hlu,

Did you drop the widgets on Front Page Content Sections?
To see the Front Page Content Section in Appearance > Customize > Widgets you have to be in the page where you have set the Front Page Template.

Also WordPress released a new version with a new editor as a widget setting.
You can disable those features and get the standard edit setting by activating this Classic Widgets plugin. Just activate it and you will see the same settings for widgets as previous.

If you have any problem let us know.

Thank you!
