Hello,

Your issue has been resolved. The issue was that you were using the custom sidebar for the shop page from the shop page. I have changed the setting to inherit from the page settings and added content in the Shop page widget area and the sidebar is displayed fine on my end.

And if you want to add more widgets then try adding the widgets to the shop page widget area under Appearance >> Widgets.

Regard’s.
