Failed to import contect.xml

Hello to the team, at the moment I have a problem with importing the xml file content.xml,
I followed all steps described in the documentation (https://docs.physcode.com/uray-wordpress-theme-documentation), but unfortunately, I can’t import the content of the XML to use it in as Demo (Part 3 in the documentation).

After running WordPress importer (Tools -> Import) errors displaying that parts of the data have not been imported (Screenshot ).

Due to this error, the pages do not display correctly on ()

My page is the following: https://carlinecosmetics.com/home-01/

Could you help to fix it, please?

Thanks
