Block products visual composer give me error

Hi,
When I place the “woocommerce product block” > https://smartaddons.s3.amazonaws.com/images/PR-templates/themeforest/wordpress/sw-fcstore/visual-composer.png in the home and select which products I want them to look at.
Don′t see a correct grid (link image):
https://oxworldwide.com/woocommerce-products.png
It’s a great problem to show the products in the home
How can I solve it?

and the customer service of the new theme doesn′t solve the problem, in fact, he doesn′t solve any problem https://themepiko.com

THx!
Alejandro
