Hi
I have deactivate all plugins, but not GP Premium + Woo + Perfect WooCommerce Brands to test, but I have the same problem : when I click to “Load More” in Brand, I go to the top of my web site.

I am not sure why the Blogs load more is showing on your woocommerce page – but you need to disable the Load More option in the Customizer > Layout > Blog
If the plugin is looking for the product selectors, then this should do:
