WIDGET not visible on page but is on DASHBOARD

Hi,
I am very new to wp.

Able to see widgets on my dashboard:

Theme mytheme with 3 Widgets

but widgets not visible when I go to my home wp page.

However when I preview the theme which by theme is based “sandbox” all of the widgets are visible on the sandbox theme page.

Any direction would be most appreciated.

Thank you.
