Hi,
Make sure you have checked all the server requirements before the theme installation – https://www.8theme.com/documentation/xstore/theme-installation/xstore-theme-requirements/
Update the theme via FTP – https://www.8theme.com/documentation/xstore/theme-installation/theme-update/ , and plugins also – https://www.8theme.com/documentation/xstore/plugins/plugins-update/
Then clear cache and check the import one more time.
Let us know the result.
Regards
