Hello, @bret,
Thank you for your response.
We recommend running an import on a fresh WordPress installation. To do this, you can use the WordPress Database Reset plugin (https://wordpress.org/plugins/wordpress-database-reset/). This plugin can be used to remove all existing content and install a new version from scratch.
Please do the reset, and import the demo site again on your site.
We kindly recommend that you take a complete backup of your site before proceeding.
We hope this helps. Should you require any further assistance, please do not hesitate to reach out. We are here to help you.
Best Regards,
The 8Theme Team
