You can change the visibility settings to hide the widget on certain pages. If you want to do that, you’ll need to select “Hide” from the dropdown menu and then select which pages to hide it on. If you don’t select any pages to hide the widget on, it will go back to being visible everywhere.
You can also choose “Show” and then choose certain pages to show the widget on, if you prefer. You can learn more about those options here: Widget Visibility
Please let me know if you have any questions about that. :)
