Hi Kyle, thanks for your quick response.
I guess I found a way to make it work. I chose Best sellers in the asset type and specified the category that I wanted. Now it works. Also, In my case, I wanted to display 18 products overall. If you set the page builder “product” element to display as much as you want (in my case 18), then the first products are going to be the best sellers, than all the other ones will follow.
I guess one of the problem seems to be some sort of lag in between when you makes changes and when they appear on the site.
For instance, I always work on the site with Safari but I’ll check the updates I made on on Chrome, so I can empty the cache (in Chrome) without being disconnected from wordpress dashboard (which I’m logged to in Safari).
