It's not possible to display the Product Categories in The Grid's Content Source so showing the grid in the WooCommerce template has no use. Showing Product Categories in the Shop page has no connection with The Grid either.
Using the WooCommerce setting above, it will display Product Categories in your Shop page out of the box so with that said, I wouldn't recommend using The Grid for this case or any customization in this case. In case you really need more information to show in your shop page, I'd recommend that you create a Global Block instead and manually adding Images, Category Titles and Category Descriptions using Image, Headline and Text elements.
Once a Global Block is created, a shortcode would be generated. For more details about Global Blocks, please see https://theme.co/apex/forum/t/global-blocks/24723
You can then use WordPress' do_shortcode function to output the global block in PHP templates like
echo do_shortcode('[cs_gb id=1796]');. You can replace
The_Grid('Camberra', true); with that.
Just note that custom code issues are not a part of our support service. Please see our Terms. Issues that will arise from suggestions given in this thread would be your responsibility to fix and enhance.
If you wish to get ask for The Grid developer's support, you will need to purchase a plugin license separately.
Thank you for understanding.
