Hi,
It does not look like you have changed anything?
1) In the SPB Sections, open “Shop Category Home List“. Inside this is wrong. Discard this.
2) I have created a new SPB Section for you to add to your page, this is called “Masonry Test“. Please edit this and you will see the correct setup. The ‘Shop Products‘ asset I have added and setup.
3) Go to your homepage and remove the include “Shop Category Home List” and replace with “Masonry Test“.
4) Set Featured Images for all your WooCommerce Products.
Follow the above and let me know how you get on.
Cheers,
David.
