Hello, Safe Desires,
Thank you for getting in touch with us.
In case you want to use the parent theme, you need to transfer Theme Options, because they are different for these themes: go to Theme Options (when the child theme is activated) > Import/Export > Download the export file. After that activate the parent theme (Appearance > Themes) > go to Theme Options > Import/Export > import your options and reload the page without saving! Save options only after reloading. Check your site after that, and use the parent theme.
If you have any additional questions or concerns, please do not hesitate to reach out to us. Our support team is always available to assist you.
Kind Regards,
8theme team
