Hello,
1) Go to Appearance > Customize > WooCommerce > Product catalog > choose what you would like to show at the shop page: categories, products or both.
2) We were able to reproduce the issue on our test installation. We’ll fix it in the next theme update. At this moment brands still inherit the shop page sidebar position http://prntscr.com/rvhkwd (Theme Options > WooCommerce > Shop > Shop page layout ) In the next update we’ll add the option to allow users choosing of the sidebar position for the brand page.
Regards
