Hello,
Thanks for contacting us.
Provide temporary wp-admin access, so we can take a closer look at the problem.
Create an account via Dashboard (Users > Add new) with administrator role http://prntscr.com/s3rc9m > provide us with username and password via the Private Content area http://prntscr.com/s5mao7 You can use any email for it.
Also, we can see this warning, contact support of the mentioned plugin – https://prnt.sc/112wlr5 , or disable this plugin.
Try to disable ALL the third-party plugins (including cache plugins), that do not come bundled with XStore https://xstore.helpscoutdocs.com/article/36-included-plugins , clear cache of your browser, and check your Home page then. Maybe one of the additional plugins causes the duplication.
Regards
