Hello,

Let’s clear up the options.

Product grid in the shop page can have 2,3,4,6 columns https://prnt.sc/p8fgil you can set it in the Theme Settings > Shop > Products columns

When you set showing both categories and products in the shop page, the number of the categories in the row will be the same as you have set in the Theme Settings > Shop > Products columns

There is a Product Category element in WP Bakery page builder which can be inserted in any page and it has the option to set 1,2,3,4,6 columns.

Best Regards
