Export function not working properly

I'm trying to export the sidebar configuration to import on a new site. I want it to appear exactly the same.

When I import it into the new site, it's copying the structure correctly. However, there is a problem. Everywhere a Visual Editor widget appears, the import file is adding the same widget, over and over. For example, if that Visual Editor widget is a photo of an apple, that apple photo is appearing every place a widget that uses the Visual Editor should be.

The widget being copied and inserted over and over is Footer Widget 3. Even when I delete it and export the sidebars, it shows up in the import.

I'm wondering if this has been reported before, and if there is any fix. Many thanks.
