Hello,
Thanks for contacting us.
BE ATTENTIVE and don’t place the private information in the general message area because all the visitors have access to that information. Use the Private Content area.
It looks like you imported a few full demos, this causes a mess of content. It is recommended to run import on a fresh WordPress installation. For this you can use WordPress Database Reset plugin https://wordpress.org/plugins/wordpress-database-reset/ The plugin can be used to remove all the existing content and install a new version from scratch. It is recommended to disable the theme https://prnt.sc/unle03 before the reset.
So do reset the current content, and do the import of the desired demo then. All should be fine then, but let us know if you need any further assistance.
Regards
