Hello,
1/ The Shop page is the default catalog page for products. It can’t be imported. Go to Theme Options > WooCommerce and change settings depends on your needs.
2/ The problem is caused by your custom changes in files – https://prnt.sc/1rjtny4 of parent theme. If you want to make changes, do them via child theme – https://xstore.helpscoutdocs.com/article/32-child-theme
Please note that we are not responsible for your custom changes.
