Number of Products displayed

Hello,

I’m trying to get the selector on my product pages to function -or- make all the products in the category show on a single page. The drop down on the page is for “Show 32 products”, “Show 64 products”, “Show 96 products”, and “Show 128 Products”. No matter what is selected, only 20 products are shown, with 4 across and 5 down.

Here’s a link: https://durangoartisanfoods.com/product-category/more-artisan-foods/

I’ve been digging around in WooCommerce settings, and here are the settings that appear relevant (but I can’t get to make the drop down work no matter what I set them to):
In Highend Options > WooCommerce Settings => Product Count = 32, Product Column = 4
Appearance -> Customize => WooCommerce -> Product Catalog -> Products per Row = 3

Can anyone help? I don’t like my customers to have to hit the page 2 button at the bottom of the page to see all the products in a certain category.

Thank you in advance!
Kara
