After installation, it does not match the demo version.

Hi,

Thank you so much for purchasing our theme and contacting our support center.

Please disable all 3rd-party plugins and then import the demo content.
We kindly ask you to deactivate all plugins and, during the import process, activate only those that are absolutely necessary.

Should you wish to perform the import process independently, please ensure to remove the previously imported demo content https://gyazo.com/37049e537d84eefd7c1101f484058a67 before importing the desired version via XStore > Import demos.

Should the issue persist, please do not hesitate to contact us again. It is very important to temporarily deactivate all third-party plugins prior to importing the demo content, as they may interfere with the process.

Warm Regards,
The 8Theme Team
